This changes the following keyframing functions to return
`SingleKeyingResult`, which is in turn used for better failure
reporting in the higher-level functions that call them:
- `KeyframeStrip::keyframe_insert()`
- `insert_vert_fcurve()`
As a side effect, this also means that
`rna_KeyframeAnimationStrip_key_insert()` can no longer return an
`FCurve *`, and now instead returns a bool indicating success.
This is part of an ongoing progressive refactor to improve error
messages and failure handling in the keyingframing code.

The goal of this PR is to remove the per face, NDC space
tracing for shadow maps.
This requires custom occluder extrapolation but in return
removes quite a lot of complexity in other areas, namely:
- No more per face transform before the tracing
- No more per face jittering (fix#119565)
- No more frustum padding (increased maximum precision)
- Better use of 32bit precision shadow map
- Fix#121343
This improve softness at relatively low step count (default 6
is better) and reduces light leaking at very low sample
count (sharper). It makes it more intuitive now that
higher sample count is smoother.

For metric units the depth was being rounded to the nearest meter
(in the range of 10-100 meters), increase the precision from 2 to 4
so it's possible to see centimeter precision.
This enables the new lazy module loading behavior introduced in OIDN 2.3,
without breaking compatibility with older versions of OIDN (using separate
code paths).
Also, the detection of OIDN support for devices is now much cleaner, and
devices do not need to be matched by PCI address or device name anymore.

BKE_mesh_validate is called by mesh.validate() Python API, as well as optionally
when doing file imports. This PR speeds it up a bit:
- Faster face data sorting by using parallel sort instead of qsort,
- One allocation for all face vertex indices, instead of a separate allocation
for each face,
- (more like a fix) Validation no longer adds a MDeformVert layer when there was
none in the input mesh.
- Small cleanups (more const inputs, etc.)
On my Windows/VS2022/Ryzen5950X machine, import time in seconds (validation on
before this PR -> validation on with this PR, validation off):
- USD (Intel Moore Lane): 9.1 -> 6.7, 4.8.
- OBJ (Blender 3.0 splash): 22.7 -> 18.6, 16.5.

This adds the same overlay that already exists for the bake node to the simulation output node.
Without this, it's quite hard to see if the simulation zone is baked or not currently.

Bezier handles are recalculated in many places in the
animation code. Threading that code can give a performance
boost all over Blender.
This patch only threads a part of the handle calculation code.
`BKE_nurb_handle_smooth_fcurve` can still be run in parallel,
but that's more complicated, so not done in this PR.
Overall this patch mostly benefits code paths that are not already threaded.

Cleanup to avoid unnecessary copies of VArray. This
requires ref-qualifier overloads of dereference operator
of attribute reader and some move operators and constructor
overloads in the code.

- Remove meaningless const for by-value arguments in declarations
- Use std::move for strings (otherwise StringRef should be used)
- Move struct to C++ namespace
- Avoid unnecessary namespace specification
- Use static constexpr instead of macros
- Add const for other arguments in function definitions
- Avoid copying struct in for loop
- Remove redundnat "private" in class
This PR fixes the ternary operation to avoid indexing into a cleared
`BitGroupVector`when trying to create an `IndexMask` for a mesh
with no hidden elements.

Remove options that are duplicate and change description of options, so
they describe bit better, how timecodes are actually used.
Timecodes in Blender have pretty much nothing in common with more widely
known term "timecode". This confused users (and developers).
There were 5 options of which 3 were exactly same. This commit leaves
user with 3 options:
- Use timecodes for normal seeking/playback - Record Run
- Ensure, that no frame is duplicated or skipped - "Record Run No Gaps"
- Do not use timecodes - "None"
More verbose description was added to the definition in code.
Naming of these timecode types was kept, even if it is incorrect to not
break scripts and habits.

Uses `FileHandlers` to handle file drag-n-drop in the space Sequencer, drop-boxes
still remain since they handle Images ID drag-n-drop.
This also allows to open/drag-n-drop multiple files at once.
When drag-and-drop is performed with a single image/movie/sound
file and only the internal `FileHandler` can be used, is used
the internal drop-box api for drag and drop, since it has a nice
drag-and-drop preview.

Mistake in a6ebfb05ad, enabled catalog list shouldn't be free'd, it just
needs to be overridden by the duplicated list correctly. Earlier a clear
(but not a free) was necessary, but now it's overridden anyway so no
clearing is needed.
Windows/Intel UHD 600 iGPUs crash when compiling probe remapping shader.
The cause is that there is a balanced barrier inside a forloop. When removing
the barrier the compilation works. This is a driver bug and most likely not
being solved as the driver maintenance mode will only be updated for critical
fixes.
This PR works around the issue making the loop condition less complex.

Detected when testing mr_elephant on an Intel HD520. When copying
the velocity buffer using the copy shader, the number of scheduled
workgroups could be larger than supported by the device.
This PR fixes this by copying multiple vertices per thread when
the work size cannot cover all the pixels.

Intel drivers on Windows platform require all varying interface data
to be written to in the previous stage.
It was detected that the world shader didn't do that as the interface
contains data used for regular objects.
There are several ways how this could be solved:
- Change nodes to use a different path for world materials.
- Include of the draw_model_lib/common_view_lib
- set the failing interface directly.
I chose to set the failing interface directly but I am fine to include
any missing library.

Multiple generations of Intel GPU have the same issue where multi
texture binding results in invalid operations where the driver
reports that the internal texture format isn't supported.
Previously this was only enabled for UHD devices, but this PR
enables it for any Intel GPU. It was detected to be faulty on
UHD600 and Iris.
