Various touchups

[C0rn3j]

Convert __init__.py to use dynamic indents to allow setting preferred indent-width.

Remove unnecessary decorators, f-strings.

Remove unnecessary importlib import (I don't see it used anywhere) and annotate the ones that are sneakily re-used in other files.

SDL_DOWNLOAD_BINARIES can return None, annotate it as such.

Touchup .gitignore for build module directories.

Remove one instance of an SDL star import in __init__.py - hopefully this is done correctly.

Add LSP/linter definitions to allow them being used properly.

@Aermoss What's the point on importing the core libraries through a file import?

from .__init__ import sys, array

It's confusing for linters/type checkers and I do not believe you get any benefit from it, since .pyc caches module imports?

It ensures that __init__.py is executed before any other file, even when a file within the module is imported directly.

It looks like it needs a few small adjustments but I'll merge it anyway, thanks a lot for the pull request!

Wouldn't that be better achieved by directly checking if it is loaded, and loading it if necessary?

if "sdl3.__init__" not in sys.modules:
  # Load __init__

The way it is done now makes it impossible to get rid of the star imports, as not doing a star import will result in doing circular imports.
