A missing `CONSTRAINT_OFF` check in `transform_convert.c` causes the
inverse matrix of that constraint to be added on top of the translation,
causing weird translation response in the viewport. Now fixed.

MakesRNA uses WITH_VULKAN_BACKEND, but it wasn't included in the
CMakeLists.txt. Also added WITH_METAL_BACKEND. Metal is currently
included as a global compilation directive. We might want to sanitize
that according in a different patch.
This PR makes sure that Vulkan backend can be selected via the PythonAPI.
Note that the changes to user preference UI isn't added to this patch as
the Vulkan backend isn't usable to end users.
`bpy.context.preferences.system.gpu_backend = 'VULKAN' should now be
possible. After saving the user preference and restarting Blender it should
initialize the Vulkan backend.

When a descriptor pool cannot allocate a descriptor set in stead
of resulting `VK_ERROR_OUT_OF_POOL_MEMORY` it is adviced that
drivers will return `VK_ERROR_FRAGMENTED_POOL`.
Before this PR the Vulkan Backend crashed as it only checked the
out of pool memory. According to the Vulkan specification it is
adviced to driver developers to report fragmented pool.
The crash happened as no new pool was allocated and no descriptor
set could be allocated anymore.
This change improved the reliability of the vulkan backend to be
able draw an animation in the 3d viewport for half an hour without
crashing. Before this change Blender would crash in a few seconds.

This PR adds the ability to only read back an area of a framebuffer
texture. It also adds the ability to read back from the depth
attachment.
Also reduces the amount of needed memory and reduces the CPU cycles
by reading back directly into the memory provided by the user. The
previous implementation wasn't able to do so as the `VKTexture::read`
function always returned a new buffer. The introduced
`VKTexture::read_sub` works on a pre-allocated buffer.

Current implementation of the Color Blend State worked for framebuffers
with a single attachment. This PR adds support for Color Blend State for
multiple attachments. It is assumed that the Blend State is the same for
all attachments.
NOTE: Integer based attachments aren't yet supported. In OpenGL it is
assumed that Integer based attachments aren't blended. It is currently
to early to tell if this is also the case for Vulkan. If this assumption
is incorrect we should use multi blend state.

This PR adds support for restart indices. Restart indices are for
example used during hair rendering where an index buffer contains
multiple hair strands. When in the index buffer a restart index is
added, a new line will start, instead of continuing extending the
previous line.

Baking simulations for an object with more than one geonodes modifier
creates cache folders for _all_ modifiers, even if some of them do not
actually have simulation zones. The simulations zones also don't need to
be connected to the output to generate cache folders.
This patch restricts cache folder generation to modifiers which actually
have simulation zones and use them.
Extra cache folders were created because executed modifiers were only
checking if a simulation state exists and not whether it contains actual
zone data (`sim_state->zone_states_.is_empty()`). The modifiers are
always executed if the object is evaluated by the depsgraph, which
happens if _any_ of the modifiers is time-dependent. Time dependency in
turn is enabled if a simulation zone exists in the tree, regardless of
whether it is used.
Checking for zone states in the cache output during baking lets us
decide if a cache folder is needed.

Adds the initial stage for the grease pencil 3.0 project.
This patch includes:
* New ID and new object type.
* New DNA structures.
* New drawing engine for grease pencil (gpencil-next).
* Tests for the new grease pencil data-type.
* A few operators for conversion, switching modes and (simple) drawing.
Exposed to the user:
* An experimental option to switch to the new grease pencil.
* This will switch the grease pencil render engine to gpencil-next which can only render the new object type.
Current grease pencil objects will no longer render.
* Changing this option currently requires a restart of blender (for the keymap to update).
* A conversion setting in the `Object` > `Convert To` operator.
* A drawing operator in `Draw Mode`.

The library is used by OBJ/PLY exporters, and asset_catalog_tree_view.
Performance of OBJ/PLY export seems to be the same. Blender executable
gets a tiny bit smaller (-5kb) on windows.
- Pasting a material would free the materials local node-tree,
leaving it in the depsgraph which would then tag the freed ID
(from deg_graph_clear_id_recalc_flags).
- texpaintslot, gp_style pointers were copied into the clipboard without
being cleared or duplicated, allowing for freed memory access later on.
- A shallow copy from the cliboard into the material could also cause
these pointers to be overwritten and leak memory.
Resolve by calling material_free_data before performing a shallow copy
and adding material_clear_data which ensures these pointers aren't
copied into the clipboard.
Commented [0] (2.5x refactor that disabled many free functions),
for some reason this call was never re-enabled.
Add back the free call along with other clipboard buffers.

When a file passed in from the command line failed to load,
blender would exit & save the quit.blend.
Resolve by adding a `do_user_exit_actions` to WM_exit_ex which is
false in backgrounds mode or when an error has occurred.
Callers to WM_exit needed to set G.is_break for a predictable exit-code.
This is error prone as G.is_break may be set based on the user having
pressed escape during event handling.
Instead, pass the exit code as an argument.
WM_exit calls `exit(G.is_break == true)` which only makes sense in
background mode, pressing escape sets `is_break` which isn't cleared,
causing an error exit-code of 1 on exit.
This would print whenever 'bpy' was imported, because in this case
Blender's Python integration loads all modules immediately because it
can't import modules as needed via the inittab mechanism.
Also correct code-comments for why inittab can't be used.
Own regression caused by [0] made to ensure the string was initialized,
without accounting for it being static & reused between calls.
Replace static variables with a struct that's passed to the function,
this explicitly shares state between calls as this static variable use
depended on BKE_scene_multiview_view_prefix_get always clearing prefix
variables with a zero view_id so future calls would also be cleared.
While this non-obvious behavior could be documented,
use more straightforward logic.

Function naming made it seem main_args_setup might need to call
main_args_setup_post, when this was in fact only needed for handing
final arguments.
Call BLI_args_parse directly and expose main_args_handle_load_file
as a public function. Move handle_load_file into a separate function
which is called by --open-last.
When a blend file failed to load from the command line,
blender would load a blend file with the path set to the location
that could not be loaded.
Now the command line argument is only treated as a new file
if the file does not already exist. Failure to load a file that
is found always exists with an error.
On click-dragging, property value was not incrementing because new
`data->dragstartx` value is infinite/invalid (when startvalue=0). To
fix this, pick max value between `startvalue` and `log_min`.
