Alternative solution to #114414 which reduces the scope of
textures for which single-channel greyscale optimization
is removed from.
Some byte buffers are converted to float buffers during
color management. These cases should retain support in
the optimal path.

Some minor tweaks to the vulkan backend to support grease pencil
drawing. The changes include:
* Add support for GPU_DATA_10_11_11_REV clearing
* Use correct index buffer start and count
Anti aliasing isn't working as they require different samplers being
configured and that require some design work.
Effects haven't been tested.

Only converted value types in the structures.
The pointer values are left unchanged as it requires more careful look
to avoid possible alignment mismatch.
Function arguments are left unchanged as well.
Only float[3] is converted as the float[4] will likely need to be
converted to some C++ rotation class. And float[4][4] often did not
compile when change is only done in the header.

Code using #PyObject_GetBuffer was combining the `PyBUF_FORMAT` and
`PyBUF_SIMPLE` flags, but the documentation specifies that
`PyBUF_FORMAT` can be |'d to any of the flags except `PyBUF_SIMPLE`
because the latter already implies format `B` (unsigned bytes).
The flags in such cases have been replaced with
`PyBUF_ND | PyBUF_FORMAT`, which has the additional requirement that the
buffer must provide it's `shape` field.
This fixes `memoryview` objects raising a `BufferError` when requested,
due to the invalid combination of flags making them be considered
invalid buffers when they would otherwise be valid.

Address regression in [0] which allowed wmKeyMapItem::properties to
remain set when a valid wmKeyMapItem::ptr can't be created because the
wmOperatorType isn't available (temporarily in the case of reloading).
Resolve by freeing wmKeyMapItem::properties when the `ptr` isn't set.
Also add null pointer check not to assume wmKeyMapItem::properties
implies an allocated wmKeyMapItem::ptr. Something which is already
accounted for everywhere else.

Avoid awkward kludges with IMB_init/exit & IMB_ffmpeg_init calls.
The animation player was responsible for calling IMB_exit, not IMB_init,
this complicated drag & drop which needed to re-internalize IMB before
returning.
Delay initializing IMB since none of the other argument handlers
depend on it, make wm_main_playanim_intern responsible for calling
both initialization & exit calls for IMB.
Also expand code comments for ARG_PASS_SETTINGS.
This was fixed by [0] however that fix didn't account for IMB
sometimes freeing GPU resources created by color management
(resolved by [1] which effectively reverted [0]).
Resolve by re-initializing IMB in the case of drag & drop.

Fix#112697: Skip unavaliable UV maps on VBO upload
The list of available UV maps is generated for the evaluated object,
however if any modifier generates UV maps (for example Geometry
Nodes) it is possible the evaluated object contains UV maps which are
not present in the base mesh. So when only the base mesh is uploaded,
for example in the UV editor, UV maps present in the list are not
guaranteed to exist.

In Blender 4.0 Grease Pencil was showing up as "Grease Pencil (legacy)" in the UI in some places.
Since the current Grease Pencil is not replaced yet, it shouldn't be named this way in 4.0.

There are two bugs with data-block inputs currently. One is #113383,
where clicking the "Clear" button on the data-block picker closes the
redo panel. The worse issue is that storing pointer properties in
operators isn't safe at all. Deleting the data-block doesn't clear
the pointer property in operator storage, for example.
The proper solution is to reuse some code from the existing data-block
picker but back it with a `session_uuid` integer property instead of an
actual pointer. This makes lookups safe without depending on the name.
However, doing that for 4.0 is too risky, so for now we will just not
support data-block inputs in the redo panel.

On some platforms `VK_FORMAT_R8G8B8_*` are not supported as vertex buffers. The
obvious workaround for this is to use `VK_FORMAT_R8G8B8A8_*`. Using unsupported
vertex formats would crash Blender as it is not able to compile the graphics
pipelines that use them.
Known platforms are:
- NVIDIA Mobile GPUs (Quadro M1000M)
- AMD Polaris (open source drivers)
This PR adds the initial workings for other unsupported vertex buffer formats we
need to fix in the future.
`VKDevice.workarounds.vertex_formats` contain booleans if the workaround for
a specific format should be turned on (`r8g8b8 = true`). `VertexFormatConverter` can be
used to identify if conversions are needed and perform the conversion.

This patch adds support for full precision compositing for the Realtime
Compositor. A new precision option was added to the compositor to change
between half and full precision compositing, where the Auto option uses
half for the viewport compositor and the interactive render compositor,
while full is used for final renders.
The compositor context now need to implement the get_precision() method
to indicate its preferred precision. Intermediate results will be stored
using the context's precision, with a number of exceptions that can use
a different precision regardless of the context's precision. For
instance, summed area tables are always stored in full float results
even if the context specified half float. Conversely, jump flooding
tables are always stored in half integer results even if the context
specified full. The former requires full float while the latter has no
use for it.
Since shaders are created for a specific precision, we need two variants
of each compositor shader to account for the context's possible
precision. However, to avoid doubling the shader info count and reduce
boilerplate code and development time, an automated mechanism was
employed. A single shader info of whatever precision needs to be added,
then, at runtime, the shader info can be adjusted to change the
precision of the outputs. That shader variant is then cached in the
static cache manager for future processing-free shader retrieval.
Therefore, the shader manager was removed in favor of a cached shader
container in the static cache manager.
A number of utilities were added to make the creation of results as well as
the retrieval of shader with the target precision easier. Further, a
number of precision-specific shaders were removed in favor of more
generic ones that utilizes the aforementioned shader retrieval
mechanism.

This was initially added a long time ago[1] to help with certain exit
behavior while running under a debugger. However, this shouldn't be
necessary any longer.
More importantly, tests have started to use the `--debug` option[2].
Somehow the bots are fine, but anyone running the tests locally on
Windows will experience what looks like a hang; unless they press a key
to allow the tests to continue.

The code from 5ac392ca4 did not work on macOS since WITH_INSTALL_PORTABLE
is not set there. This issue was hidden before, but now happens due to
the changes in #114569 to avoid using /etc/ssl.
Cleanup talked about in the previous semi-related PR, #114501
- saacos, saasin, sasqrt have been 100% identical to saacosf,
saasinf, sasqrtf since 2012.
- For all the above, there exist more intuitively named safe_acosf,
safe_asinf, safe_sqrtf that do the same thing, so switch all code to those.

The Cryptomatte node is not searchable in the link drag search operator.
That's because it still uses socket templates, which are no longer
supported for search since f5e6d4e4b0.
This patch fixes that by using the declare method instead of socket
templates.

acos() usage in all places related to normal calculations shows up in the
profiler. Given that "angle between faces" is only additional heuristic
weight in there (the effect of it at all is very subtle), approximate but
faster version of acos() might be just fine. Especially since some other
parts of Blender (e.g. mikktspace) use approximate acos in a conceptually
the same part.
- Adds safe_acos_approx() to BLI_math_base.hh. Implementation the same
as already exists in Cycles; max error 0.00258 degrees. Between 2x and 4x
faster in my tests.
- Changes all normals related calculations to use the function above instead
of saacos.
Computing normals on a Stanford Lucy (14m verts) mesh:
- Mac (arm64, M1 Max): 247ms -> 229ms
- Win (x64, Ryzen 5950X): 276ms -> 250ms
All places that are about "normal calculation" were changed, including e.g.
Corrective Smooth modifier. Applying that one to the same 14m vertices mesh,
Mac M1 Max: 9.96s -> 9.76s
Tiny changes in several test output expectations w.r.t. normals are
observed, these were reviewed and updated expectations checked in svn.

Extract:
- "Attribute", when creating a new attribute with
`GEOMETRY_OT_attribute_add()`: make the default name in the operator
a null string, and set it to "Attribute" translated inside an invoke
method instead.
- Also for new attributes, from `BKE_id_attribute_calc_unique_name()`,
for instance to create a default vertex color layer when going into
Vertex Paint mode: use `DATA_()` instead of `IFACE_()`, since it
represents user data.
Disambiguate:
- "Weight" can be the thickness of font glyphs.
- "Mark as Asset" and "Clear Asset" are operator names already
extracted using the Operator context. They were recently added to a
manual translation in the UI, but the existing one can be reused.
- "Second" as a time unit in the context of frame snapping.
