d7f124f06f Fix T102845: GPU python crash in background mode 
`BPYGPU_IS_INIT_OR_ERROR_OBJ` is not implemented in all pygpu functions.

Instead of copying and pasting that call across the API when it has no
gpu context, override the methods with one that always reports error.

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++.

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

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.

04b6296e81 Python GPU: Add reference of PyObject GPU object to the GPU object itself 
Instead of creating different python wrappers for the same GPU object,
return the same `PyObject` created earlier.

This also allows for more secure access to existing GPU objects.
