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 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.
Pull Request: https://projects.blender.org/blender/blender/pulls/118010
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).
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.

Implements the design from #116067.
The socket type is called "Matrix" but it is often referred to as "Transform"
when that's what it is semantically. The attribute type is "4x4 Matrix" since
that's a lower level choice. Currently matrix sockets are always passed
around internally as `float4x4`, but that can be optimized in the future
when smaller types would give the same behavior.
A new "Matrix" utilities category has the following set of initial nodes"
- **Combine Transform**
- **Separate Transform**
- **Multiply Matrices**
- **Transform Direction**
- **Transform Vector**
- **Invert Matrix**
- **Transpose Matrix**
The nodes and socket type are behind an experimental flag for now,
which will give us time to make sure it's the right set of initial nodes.
The viewer node overlay doesn't support matrices-- they aren't supported
for rendering in general. They also aren't supported in the modifier interface
currently. But they are supported in the spreadsheet, where the value is
displayed in a tooltip.

Currently most of the data stored in `wmWindowManager` is runtime
data not saved to files. It's confusing that it's declared in DNA then. That
also prevents us from using C++ features. This commit adds an initial
runtime struct. Moving data there can be done as a separate step.
Initially I wanted to look at moving the `ReportList` system to C++.
The runtime struct has to be defined in the blenkernel module because
the members are (will be) used there in a few places.

The Translate node crashed for single inputs in the Full Frame
compositor, that's because it always assumed image inputs. So fix this
by handling the single value case.
The ID remapper code was already largely defined in a CPP struct
(IDRemapper). Make this an actual class, and remove the C API wrapper
around.
This makes the code cleaner, easier to follow, and easier to extend or
modify in the future.

Running background mode now behaves as if the "-noaudio" was passed in.
The -setaudio command now has a "Default" option which can be used
in the rare cases audio playback is desired in background mode. e.g.
blender --background -setaudio Default
