Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:

This patch improves how debug groups are displayed
within captures. Passes are now split to align with
debug groups, such that navigation of captures is
more intuitive.
To closer represent useful information, debug groups are now
deferred to align with passes, with the addition of Macros to
control capture display options.
METAL_DEBUG_CAPTURE_MAX_NESTED_GROUPS limits debug
group nesting, and METAL_DEBUG_CAPTURE_HIDE_EMPTY allows
hiding of debug groups which do not contain any commands.

This covers implementation of the GPUTexture abstraction for the Metal backend, with additional utility functionality as required.
Some components have been temporarily disabled pending dependencies on upcoming Metal backend components, and these will be addressed as the backend is fleshed out.
One core challenge addressed in the Metal backend is the requirement for read/update routines for textures. MTLBlitCommandEncoders offer a limited range of the full functionality provided by OpenGLs texture update and read functions such that a series of compute kernels have been implemented to provide advanced functionality such as data format conversion and partial/swizzled component updates.
This diff is provided in full, but if further division is required for purposes of code review, this can be done.
