8929ed75d4 Image: Add OIIO support APIs 
This adds a new set of APIs supporting the loading and saving of image
formats through OIIO. It makes use of the recent IOProxy work in OIIO
to align with the existing Blender image loading/saving machinery.

The support code here has been prototyped to work with ~7 of our image
formats so far. It includes centralized handling of `IB_test`,
`IB_mem`, and `IB_metadata` flags, which the existing code did not
handle consistently or at all depending on the format.

The PSD format (`format_psd.cc`) is included since the prior location
of the code has been restructured away. It serves as an example of how
the loading code typically flows for all the other formats.

e424931cf7 Cleanup: rename Byte to Bytes in Python string utilities 
These functions operate on byte arrays, not a single byte,
match naming for CPython's PyBytes_AS_STRING.

4eb9322eda Cleanup: PyMethodDef formatting 
Missed these changes in [0].

Also replace designated initializers in some C code, as it's not used
often and would need to be removed when converting to C++.

e555ede626 Cleanup: unify struct declaration style for Python types, update names 
Use struct identifiers in comments before the value.
This has some advantages:

- The struct identifiers didn't mix well with other code-comments,
  where other comments were wrapped onto the next line.
- Minor changes could re-align all other comments in the struct.
- PyVarObject_HEAD_INIT & tp_name are no longer placed on the same line.

Remove overly verbose comments copied from PyTypeObject (Python v2.x),
these aren't especially helpful and get outdated.

Also corrected some outdated names:

- PyTypeObject.tp_print -> tp_vectorcall_offset
- PyTypeObject.tp_reserved -> tp_as_async

84756b68e6 Add documentation about Image/ImBuf to python/RNA API. 
Related to T95616, the relationship between Image ID and ImBuf 'cached'
buffers can be fairly confusing when using the RNA API.

982aea88e0 Cleanup: separate format-units for Python argument parsing 
With the increased use of multi-character format units and keyword-only
arguments these are increasingly difficult to make sense of.

Split the string onto multiple lines, one per argument.
While verbose it's easier to understand and add new arguments.

c434782e3a File headers: SPDX License migration 
Use a shorter/simpler license convention, stops the header taking so
much space.

Follow the SPDX license specification: https://spdx.org/licenses

- C/C++/objc/objc++
- Python
- Shell Scripts
- CMake, GNUmakefile

While most of the source tree has been included

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
  use different header conventions.

doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

cd9acfed4f Cleanup: use preprocessor version check for PyTypeObject declaration 
While `tp_print` was deprecated, Python 3.8+ uses this for
'tp_vectorcall_offset' which wasn't stated in the comment from
efd71aad4f.

Instead of suppressing clang-tidy, use preprocessor a check since
this properly represents the difference between Python versions.

- BEGIN/END license blocks

  Developers should add non license comments as separate comment blocks.
  No need for separator text.

- Contributors

  This is often invalid, outdated or misleading
  especially when splitting files.

  It's more useful to git-blame to find out who has developed the code.
