When closing the blender, while the callbacks are removed, the
reference count of the object used as `customdata` is not decremented.
This commit adds two functions that correctly release the
python `draw_callbacks` before releasing all `draw_callbacks`.

Support Python 3.10a5 or 3.9x with support explicitly enabled.
- Enable Python's postponed annotations for Blender's RNA classes
types registered on startup.
- Using postponed annotations has implications for how they are defined,
since they must evaluate in the modules name-space instead of the
classes name-space. See changes to annotations in `release/scripts`.
- Use `from __future__ import annotations` at the top of the module
to ensure the script will run with Python 3.10.
- Old logic is kept since it could be used if PEP-649 is supported.

Ref D10474
Use Python 3.8's API for setting the initial configuration.
This replaces a mix of our logic and direct calls to the Python API
and has no user visible changes.
Using the Python API makes the logic easier to follow and provides
utilities such as `PyConfig_SetBytesArgv`
that wasn't available in previous releases.
Note that this uses Python's utf8/wchar_t conversions,
which used to cause problems (see T31506).
Since `Py_UTF8Mode` was set, the systems locale isn't used for decoding,
allowing us to use Python's utility functions that call
`Py_DecodeLocale` internally.
Ref D10382
Removes two unused --debug-gpu command line flags (unused as in, does nothing):
* `--debug-gpumem`: Unused since c08d847488, the info is now available in
the status-bar if enabled in the Preferences. Initially added in
fec317de8d.
* `--debug-gpu-shaders`: Unused since 216d78687d, double checked with
Clément, he says it's not that useful nowadays. Initially added in
fec317de8d.
Addresses T83954 and T83953.

System encoding issues have been a paint-point for us with Python 3,
since Blender always uses UTF-8 which might not be the case for the OS.
While the Py_SetStandardStreamEncoding was already set to utf-8,
the file-system could still have an incompatible encoding.
See PEP-540 for details.
BPY_context_dict_clear_members_array used PyDict_DelItemString
which raised & cleared the exception when the key didn't exist.
Even though setting/clearing the exception is supported,
it's worth avoiding where possible as it adds some overhead as well as
overwriting the previous error which can free PyObject's which are
unrelated to the code being executed.
Possible fix for T82552, crashing on Windows when setting the exception.
Sometimes multiple calls to `bpy.data.orphans_purge()` are needed to
delete all orphans, because a call can turn previously-used datablocks
into orphans. Returning the number of deleted datablocks makes it
possible to keep looping until nothing can be deleted any more.
This patch keeps track of deletions in `id_delete()` so that it can be
returned up the call stack.

Remove DNA headers, using forward declarations where possible.
Also removed duplicate header, header including it's self
and unnecessary inclusion of libc system headers from BKE header.
While `tp_print` was deprecated, Python 3.8+ uses this for
'tp_vectorcall_offset' which wasn't stated in the comment from

Instead of suppressing clang-tidy, use preprocessor a check since
this properly represents the difference between Python versions.
Fixes 18 misspellings of 'predefined', 'Look Up', 'Lookup', and 'No One'.

This was added when Python was initially bundled so any problems
finding Python could be investigated.
Move this to use logging so we can show this information when needed.
