Essentially, our current code would not properly remove (dereference)
its python objects matching various RNA data created during execution.
Some cases are fairly trivial to understand (like the lack of handling
of unregstering for our 'startup' operators and UI), other were more
subtle (like unregistered PropertyGroups who would remove/free their RNA
struct definition, without releasing first the potential matching python
object).

Parallel shader compilation introduced `GPU_shader_cache_dir_clear_old`.
The implementation was specific to OpenGL and could not be overwritten
by other backends. This PR improves the implementation so the backend
can have its own implementation.
This is needed for upcoming changes to the Vulkan backend where we
want to use similar mechanisms to speed up shader compilation and caching.

Move the shader cache to `BKE_appdir_folder_caches`, since the
temporary folder is reset on Linux on every system restart.
Manually delete shader cache files on Blender exit if they have not
been used for more than 30 days.

The call to `GHOST_DisposeSystemPaths` was done in `WM_exit_ex` and
_some_ of the tests' 'teardown'. But some more where missing. Issue was
only reproducible when defining `WITH_CXX_GUARDEDALLOC` cmake option.
There are several layers of issues here, this commit addresses the
first, simplest one: since `BKE_appdir` API will indirectly create the
GHOST SystemPaths data, it is simpler and more logical to move the
deletion of this SystemPaths data in `BKE_appdir_exit()`. This avoids
exposing a fairly low-level implementation detail all over our codebase.
Further more, `WM_init` also does not need to explicitely call
`GHOST_CreateSystemPaths`, since it will be created automatically when
required.
All add-ons were being scanned at startup, while this didn't cause
errors it was noticeable with extensions where any errors in the
manifest were being reported at startup, even when running with
factory-startup (including blender's own tests).
Address two issues:
- The logic to "reset" add-ons, so as to match the preferences when
reverting or resetting preferences always ran on startup.
This occurred because a check for Python being initialized was
incorrectly used to detect that this wasn't the first time preferences
were being loaded (regression in [0]).
- Resetting add-ons scanned all add-ons (including disabled add-ons) to
ensure their module cache is up to date. Since this the cache is
lazily initialized, it's simpler to set it as uninitialized as
resetting the add-ons doesn't require the cached meta-data.

This implements all the sculpt tools in Grease Pencil 3.
UI changes in the 3D view header and keymap entries for sculpt mode are
still minimal, more entries should be added once the relevant operators
are supported.
A set of utility functions and a shared base class
`GreasePencilStrokeOperationCommon` for sculpt operations has been added
to make individual operations less verbose.
The `GreasePencilStrokeParams` struct bundles common arguments to reduce
the amount of boilerplate code. The `foreach_editable_drawing` utility
function takes care of setting up the parameters and finding the right
drawings, so the tool only has to modify the data. Common features like
tracking mouse movement and inverting brush influence are handled by the
common base class.
Most operations are then relatively simple, with the exception of the
Grab and Clone operations.
- __Grab__ stores a stroke mask and weights on initialization of the
stroke, rather than working with the usual selection mask.
- __Clone__ needs access to the clipboard, which requires exposing the
clipboard in the editor API.

Move most code to `blender::bke::subdiv`. That helps organization
and makes using C++ in subdiv code easier, which will be useful for
removing the unnecessary opensubdiv C-API wrapper.
Add support for add-ons to define commands using the new argument
`-c` or `--command`.
Commands behave as follows:
- Passing in a command enables background mode without the need to pass
in `--background`.
- All arguments following the command are passed to the command
(without the need to use the `--` argument).
- Add-ons can define their own commands via
`bpy.utils.register_cli_command` (see examples in API docs).
- Passing in `--command help` lists all available commands.

In many modes, Blender uses the `MemFile` undo step, which serializes all DNA
data in RAM almost as if writing a .blend file. For auto-save, Blender used to
write the last `MemFile` undo step to disk because that was faster serializing
all of DNA again. Furthermore, saving the `quit.blend` file when closing Blender
also used this.
This functionality is now removed in preparate for supporting implicit sharing
in the undo system (#106903). Auto-save and saving the quit.blend file now use
regular file saving.
The removal of this feature and its implications have also been discussed here:
https://devtalk.blender.org/t/remove-support-for-saving-memfile-undo-steps-as-blend-files-proposal/33544
Auto-save currently only really works in modes that use the `MemFile` undo step,
that excludes things like mesh edit and sculpt mode. Previously, Blender would
attempt to auto-save in those modes, but it would only save the last state from
before the mode was entered, which is useless when staying in the mode for longer.
This problem is *not* fixed here. However, the code now explicitly skips auto-saving
in order to avoid unnecessary short freezes in these modes when Blender auto-saves.
Furthermore, the auto-save will now happen when changing modes.
This reduces the impact of save-time-regressions with #106903.

This PR adds a new command line argument to validate all statically
defined shaders. It is useful for platform support to understand
what isn't working.
It only checks statically defined shaders. Dynamic shaders (EEVEE/Compositor)
can still be fail.
The report is printed to console. After checking with windows platform and
triaging we could also add it to gpu debug script. There is a risk of adding it there
as it might crash and don't store any output.

Overall the transition to C++ in the draw module is awkwardly half
complete, but moving more code to a C++ namespace makes cleaning up
this code in other ways much easier, and the next C++ cleanup steps
are clear anyway.
This is a smaller rewrite/refactor of the VSE copy paste code to use the file copy buffer logic that is used in other places of Blender.
This makes Blender able to copy paste between Blender processes.
It can also paste successfully after closing and reopening Blender.
Other than that, the functionally should remain the exact same as the current copy paste operator with one exception: Scene strips does not retain their scene pointer when pasting into the same file.
This is to make it consistent with how it was before when copy pasting between .blend files.
(The scene data for the scene strips were never copied in when doing that)
Logic for pulling in or linking scenes into new or current files are purposely left for later when a proper proposal of how this would work in a nice fashion is done.
Now the strip data gets copied either fully or partially besides for scene strips. There only the script data gets copied and not the scene data.
If there is a audio/video data block of the same name as in the paste data, it will be reused to reduce potential duplication of data.

This was initially added a long time ago[1] to help with certain exit
behavior while running under a debugger. However, this shouldn't be
necessary any longer.
More importantly, tests have started to use the `--debug` option[2].
Somehow the bots are fine, but anyone running the tests locally on
Windows will experience what looks like a hang; unless they press a key
to allow the tests to continue.

After this commits from main were pushed to blender-v4.0-release. These are
being reverted.
Commits a4880576dc from to b26f176d1a that happend afterwards were meant for
4.0, and their contents is preserved.
