The `object_to_world` and `world_to_object` matrices are set during
depsgraph evaluation, calculated from the object's animated location,
rotation, scale, parenting, and constraints. It's confusing and
unnecessary to store them with the original data in DNA.
This commit moves them to `ObjectRuntime` and moves the matrices to
use the C++ `float4x4` type, giving the potential for simplified code
using the C++ abstractions. The matrices are accessible with functions
on `Object` directly since they are used so commonly. Though for write
access, directly using the runtime struct is necessary.
The inverse `world_to_object` matrix is often calculated before it's
used, even though it's calculated as part of depsgraph evaluation.
Long term we might not want to store this in `ObjectRuntime` at all,
and just calculate it on demand. Or at least we should remove the
redundant calculations. That should be done separately though.

The Realtime Compositor uses the CPU compositor. That's because the enum
identifier of the Realtime Compositor changed to GPU, so update the test
script accordingly.
The tiled compositor code is mainly still around, which is only
expected to be a short-lived period. Eventually it will also be
removed.
The OpenCL, Group Buffers, and Chunk size options are already removed.

This improves the volume probe resolution and
dimensions to envelope most test scenes.
This doesn't increase the baking time
that much as most of the baking time is
spent compiling shaders.
Caused by previous change for full-frame compositor.
The determine_canvas() is still used by the tiled compositor,
so restore it to the state which makes both compositors to work.

This aligns the node behavior to GPU compositor.
The implementation is a bit of a stretch of the full-frame
constant-foldable operations, but this is as good as it can
get in a short time.
The alternative could be to somehow inject a SetValue
operation, but since it expects ahead-of-time known value it
is not as straight forward.

The convex hull tests included a reference AABB-fitting function for
comparison which was used to validate the optimized implementation.
This wasn't great as it depended on matching exact return values and
didn't test the logic of AABB-fitting worked usefully.
Replace this with a more general test that creates random polygons with
known bounds, apply a random rotation & translation, then use
AABB-fitting to un-rotate the points, passing when the bounds are no
larger than the size of the generated input.
Details:
- Make BLI_convexhull_aabb_fit_hull_2d a static function again as it was
only exposed for tests. Use BLI_convexhull_aabb_fit_points_2d instead.
- Remove brute force reference implementation from tests,
moving this to an assertion within convexhull_2d
(disabled by default since it's quite slow).
As this is only added to set strict warnings, cleaning logic would
remove as the compilers output is unchanged.
Support excluding headers from removal, others can be added if needed.
Turns out we were not building OSL with OptiX enabled anymore.
Also check now if the OSL builds has OptiX support and if not
disable it in Cycles.
Building OSL with support for this (still) does not require
either the OptiX SDK or CUDA, it only needs LLVM.

The lack of these functions in the "single trivial value" and "sliced
GVArray" implementations caused some code to call fack to the base
class functions. Those are much slower since they involve a virtual
function call per element. For example, this changed the runtime of
creating a new boolean attribute set to "true" on one million faces
from 3.4 ms to 0.35 ms.
