We can't use the `threshold` uniform name in Metal because it is used as
a local variable in one of the library files, because uniforms are
defines in Metal, so it causes an error. Change the name to
`color_threshold` as a fix.
This implements the proposal from #124512. For that it contains the following
changes:
* Remove the global override of `new`/`delete` when `WITH_CXX_GUARDEDALLOC` was
enabled.
* Always use `MEM_CXX_CLASS_ALLOC_FUNCS` where it is currently used. This used
to be guarded by `WITH_CXX_GUARDEDALLOC` in some but not all cases. This means
that a few classes which didn't use our guarded allocator by default before,
are now using it.

NOTE: This also required some changes to Cycles code itself, who is now
directly including `BKE_image.hh` instead of declaring a few prototypes
of these functions in its `blender/utils.h` header (due to C++ functions
names mangling, this was not working anymore).

The Double Edge Mask node uses too much memory when it is not connected
to anything in the Full-Frame compositor. That's because it tries to
allocate a buffer of size 131072x131072, which is due to the cumulation
of multiple issues.
1. The Full-Frame compositor evaluates nodes that are not connected to
the output.
2. The constant folder assigns a bounds of +-65536 to its output memory
buffers as a maximum possible value.
3. Then the MemoryBuffer::inflate method doesn't know about the constant
folder special value, so it tries to allocate a buffer of that size.
The safest fix for now is to clear the output and return early if all
inputs are single value.
The problem is that this issue might happen for other nodes that also
satisfy the 3 issues above, that is, uses inflate and can be constant
folded. I manually checked for such nodes and there are no nodes that
satisfy all three, so hopefully this is isolated to the Double Edge Mask
node.

For C/C++ doc-strings should be located in headers,
move function comments into the headers, in some cases merging
with existing doc-strings, in other cases, moving implementation
notes into the function body.
The Cryptomatte node produces a bad output when the viewport is in
camera view. That's because compositing is limited to the camera region
in that case, but the node assumes the full viewport size. To fix this,
only consider the compositing region instead of the full viewport.
When the compositor is canceled mid-execution, the image node will get
corrupt in future executions in new CPU execution mode. That's because
the image node treated cached images as an intermediate results that can
be passed through, while they should be treated as external resources
since they are managed by the static cache manager.
This patch fixes that by adding another variant of wrap_external that
takes a Result and wraps its data, then we use that in the Image node.
Blender leaks memory when the compositor gets canceled. That's because
later operations in the compositor are responsible for freeing the
results of earlier operations, so when the compositor gets canceled
before all operations got the chance to execute, memory will be leaked.
To fix this, force free all operations when the compositor gets
canceled.
This patch adds support for passes in the new CPU compositor. This
involves rewriting the get_input_texture method into a get_pass methods
that returns a result as opposed to a texture. The result wraps the
cached GPU texture or image buffer depending on the execution device.
The Render Layers node was implemented for CPU execution and a new
utility constructor for the result class was added to determine type and
precision based on GPU texture format. The fallback depth pass that was
retrieved from the viewport frame buffer was removed, as it was a hack
that can no longer be supported due to the use of stencil format.

This avoid cmake shenanigans to try to make proper
dependency tracking.
The previous code was not tracking changes inside
the create info files.
There is no real benefit for having these headers listed in
the cmakefile itself.
