Switch 3.2.14 Port

[vs49688]

Port of the Switch patches to SDL 3.2.14.

Based off the upstream release-3-2.14 tag (8d60435), and switch-sdl-2.28 (78899b6) plus a few of my changes here.

Unfortunately, the diff is too great for easy rebasing, so I'm taking the changes as-is and integrating them as-is.

Current component status:

• audio - Tested, working
• filesystem - Tested, working
• joystick - Tested, working
• power - Untested
• timers - Tested, SDL3 hard-requirement.
• video
  • OpenGL/EGL - Tested, working
  • keyboard - Untested
  • mouse - Tested, working
  • swkb - Untested
  • touch - Untested
  • video - Tested, working
• threads - Tested, SDL3 hard-requirement

With the exception of the first commit, there's three commits per subsystem.

1. The "seed" commit, i.e. a straight copy/paste of the files from the original branch.
2. The reformat commit, using SDL's .clang-format
3. The port itself.

A note about the video subsystem - the seed is slightly different from the original, as it contains some extra commits changes I did earlier, specifically vs49688@1a9aa28 and vs49688@bf33c98

I would appreciate it if someone could test power, keyboard, swkb, and touch, if possible. I don't have anything that uses them.
