Using the attribute name semantics from T97452, this patch moves the
selection status of mesh elements from the `SELECT` of vertices, and
edges, and the `ME_FACE_SEL` of faces to generic boolean attribute
Storing this data as generic attributes can significantly simplify and
improve code, as described in T95965.
The attributes are called `.select_vert`, `.select_edge`, and
`.select_poly`. The `.` prefix means they are "UI attributes",so they
still contain original data edited by users, but they aren't meant to
be accessed procedurally by the user in arbitrary situations. They are
also be hidden in the spreadsheet and the attribute list.
Until 4.0, the attributes are still written to and read from the mesh
in the old way, so neither forward nor backward compatibility are
affected. This means memory requirements will be increased by one byte
per element when selection is used. When the flags are removed
completely, requirements will decrease.
Further notes:
* The `MVert` flag is empty at runtime now, so it can be ignored.
* `BMesh` is unchanged, otherwise the change would be much larger.
* Many tests have slightly different results, since the selection
attribute uses more generic propagation. Previously you couldn't
really rely on edit mode selections being propagated procedurally.
Now it mostly works as expected.

The mesh's triangulation cache is often created for other operations
besides the drawing code, but during the mesh draw cache extraction
it is recalculated on every single time. It is simpler and faster to use
the existing MLoopTri array. It can also save memory if the cache
already exists by avoiding allocating a duplicate array. For a 4 million
face quad mesh, that is already 128 MB.
Also use face normals for mesh triangulation if they aren't dirty,
which should provide a general speedup when they're both necessary.
Recently 54182e4925 made this more reliable, since the triangulation
cache is invalidated properly when the mesh is deformed.

Similar to the other refactors from T95965, this commit moves sculpt
face sets to use a generic integer attribute named `".sculpt_face_set"`.
This makes face sets accessible in the Python API.
The attribute is not visible in the attributes list or the spreadsheet
because it is meant for internal use, though that could be an option
in the future along with other similar attributes. Currently the change
is small, but in the future this could simplify code by allowing use
of more generic attribute APIs.

Points cannot be selected atm in editmode, this patch just shows the
selection from sculptmode in editmode.
Since the selection in sculptmode is a float, a point is considered
selected as soon as the float selection is above 0.0f.
Implementation: this piggy-back on the existing drawing via
overlay_edit_curve_point.glsl which requires a "data" VBO which holds
flags for selection (next to others such as "active" - which we also
have to take care of later).

This is required by the Metal backend to perform flushing of temporary objective-C resources. This is implemented as a global autoreleasepool, and is to ensure consistency such that all rendering operations, whether called via events, or via main loop will be within an autoreleasepool.

For the Metal shader translation support for shader-global uniforms are remapped via macro's, and in such cases where a uniform name matches a vertex attribute name, compilation errors will occur due to this injected syntax being incompatible with the immediate code.
Also adding source-level function interface alternatives where sized arrays are passed in. These are not supported directly in Metal shading language and are instead handled as pointers. These pointers require explicit address-space qualifiers in some cases, if device/constant address space memory is passed into the function.

These implementations remove dependency on the Geometry pass by instead invoking one vertex shader instance for each expected output vertex, matching what a geometry shader would emit. Each vertex shader instance is then responsible for calculating the same output position based on its vertex_id as the logic would in the geometry shader version.
SSBO Vertex fetch enables full random-access into a vertex buffer by binding it as a read-only SSBO. This enables each instance to read neighbouring vertex data to perform contextual calculations as a geometry shader would, for cases where attribute Multiload is not supported.

MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.

Smooth flag should come from the evaluated mesh, only selection and hidding
state should be mapped to the original bmesh.
Pre-existing issue revealed by refactor in b247588dc0.
Sun Disc is currently not supported because it'll need special handling - on the one hand, I'm not sure if Eevee would handle a 1e6 coming out of a background shader without issues, and on the other hand it won't actually cast sharp shadows anyways.
I guess we'd want to internally add a sun to the lamps if Sun Disc is enabled, but getting that right is tricky since the user could e.g. swap RGB channels in the node tree and the lamp wouldn't match that.
Anyways, that can be handled later, the sky itself is already a start.

This reverts commit 34051fcc12.
Although for normal use this doesn't make a difference. But when working with
huge scenes and volumetrics + NVIDIA it made a work-around not possible anymore.
For the heist production we added a fix on the render-farm (enable GPU workarounds).

When a change happens which invalidates view layers the syncing will be postponed until the first usage.
This will improve importing or adding many objects in a single operation/script.
`BKE_view_layer_need_resync_tag` is used to tag the view layer to be out of sync. Before accessing
`BKE_view_layer_active_base_get`, `BKE_view_layer_active_object_get`, `BKE_view_layer_active_collection`
or `BKE_view_layer_object_bases` the caller should call `BKE_view_layer_synced_ensure`.
Having two functions ensures that partial syncing could be added as smaller patches in the future. Tagging a
view layer out of sync could be replaced with a partial sync. Eventually the number of full resyncs could be
reduced. After all tagging has been replaced with partial syncs the ensure_sync could be phased out.
This patch has been added to discuss the details and consequences of the current approach. For clarity
the call to BKE_view_layer_ensure_sync is placed close to the getters.
In the future this could be placed in more strategical places to reduce the number of calls or improve
performance. Finding those strategical places isn't that clear. When multiple operations are grouped
in a single script you might want to always check for resync.
Some areas found that can be improved. This list isn't complete.
These areas aren't addressed by this patch as these changes would be hard to detect to the reviewer.
The idea is to add changes to these areas as a separate patch. It might be that the initial commit would reduce
performance compared to master, but will be fixed by the additional patches.
**Object duplication**
During object duplication the syncing is temporarily disabled. With this patch this isn't useful as when disabled
the view_layer is accessed to locate bases. This can be improved by first locating the source bases, then duplicate
and sync and locate the new bases. Will be solved in a separate patch for clarity reasons ({D15886}).
**Object add**
`BKE_object_add` not only adds a new object, but also selects and activates the new base. This requires the
view_layer to be resynced. Some callers reverse the selection and activation (See `get_new_constraint_target`).
We should make the selection and activation optional. This would make it possible to add multiple objects
without having to resync per object.
**Postpone Activate Base**
Setting the basact is done in many locations. They follow a rule as after an action find the base and set
the basact. Finding the base could require a resync. The idea is to store in the view_layer the object which
base will be set in the basact during the next sync, reducing the times resyncing needs to happen.

On NVIDIA volumetric resolve failed for large production scenes.
The result would remove most color from the final render. The cause
seems to be a faulty driver.
This change ported the fragment shader to a compute shader which
would select a different compiler branch and didn't show the error.
This change adds cryptomatte render passes to EEVEE-Next. Due to the upcoming viewport
compositor we also improved cryptomatte so it will be real-time. This also allows viewing
the cryptomatte passes in the viewport directly.
{F13482749}
A surface shader would store any active cryptomatte layer to a texture. Object hash is stored
as R, Asset hash as G and Material hash as B. Hashes are only calculated when the cryptomatte
layer is active to reduce any unneeded work.
During film accumulation the hashes are separated and stored in a texture array that matches
the cryptomatte standard. For the real-time use case sorting is skipped. For final rendering
the samples are sorted and normalized.
NOTE: Eventually we should also do sample normalization in the viewport in order to extract the correct
mask when using the viewport compositor.

Currently, when subdividing every single vertex on every loose edge,
Blender iterates over all other edges to find neighbors. This has
quadratic runtime and can be very slow. Instead, first create a
map of edges connected to each vertex.
With about 10000 edges, the performance goes from very slow to very
smooth in my tests. Because of the nature of quadratic runtime, the
improvement will depend massively on the number of elements.
The only downside to this is that the map will still be built when
there are only a couple loose edges, but that case is probably not
so common.
