b3cdeb942a opengl: default to vsync=0 everywhere. 
This reverts commit 3ee29f2e7a, among other
changes. This means getting a scary warning on the javascript console in
Emscripten by default, but this is easily fixed by setting a GL swap
interval at startup or creating a 2D renderer with the appropriate property
(or call to SDL_SetRenderVSync()).

Fixes #14625.

2ffabb5150 render: Fix texture format selection for color-keyed indexed surfaces 
015cc6a broke texture format selection for this kind of surface if the
renderer's first texture format doesn't happen to have an alpha
channel. This happens for on-screen software renderers on Windows,
whose preferred format is the window's own `SDL_PIXELFORMAT_XRGB8888`.
This fixed check also cover the intent behind 015cc6a, assuming that
indexed and alpha formats are mutually exclusive.

3316dde0c2 Improved error information when renderer creation fails 
On Android, if you create a window with SDL_WINDOW_OPENGL, you can't create a Vulkan surface. The error message has been improved to reflect this, and the error is propagated back up to the application.

Also added warn level logging if the renderer couldn't be created.

2a01e12d34 Simplify palette code 
Each texture gets its own palette, the palette is updated when it is rendered if necessary, rendering is flushed if a texture render is already queued up.

Trying to share palettes and handle the different cases of queued rendering and changing palettes in the middle of the frame ends up being very complicated, so we'll keep it simple for now.

ee1c90a358 Improved handling of function parameter validation 
SDL supports the following use cases:
 * Normal operation with fast parameter checks (default):
    SDL_SetHint(SDL_HINT_INVALID_PARAM_CHECKS, "1");
 * Object parameters are checked for use-after-free issues:
    SDL_SetHint(SDL_HINT_INVALID_PARAM_CHECKS, "2");
 * Enable full validation, plus assert on invalid parameters:
    #define SDL_ASSERT_INVALID_PARAMS
 * Disable all parameter validation:
    #define SDL_DISABLE_INVALID_PARAMS

07ef532681 hints: Renamed SDL_HINT_LOG_BACKENDS to SDL_DEBUG_LOGGING. 
This still logs backend choices, but we might use it for other things. For
example, what Android device is being used, or all the devices we enumerated,
etc.

Ideally this eventually logs all the stuff we often have to ask followup
questions about.
