e23257307e Introduce formal policy for APIs that return strings. 
This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.

This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.

Fixes #9902.

(and several FIXMEs, both known and yet-undocumented.)

edaab8ad9f Refactored audio conversion to reduce copying 
More of the logic has been moved into SDL_AudioQueue,
allowing data to be converted directly from the input buffer.

8f6f9cadc4 Rewrote audio resampler using cubic filter interpolation 
This allows using a much smaller (1.5 KB) lookup table, in exchange for a small amount of extra work per frame.

The extra work (a few extra loads/mul/adds) is negligible, and can execute in parallel.
The reduction in cache misses almost certainly outweighs any added cost.

The table is generated at runtime, and takes less than 0.02ms on my computer.

ccae9c1ef6 Only initialize audio drivers that have been requested 
If testautomation is running with only a specific audio driver enabled, we shouldn't try to open other ones, as they might fail.

Fixes https://github.com/libsdl-org/SDL/issues/8797

(cherry picked from commit 4c11307a4e)

c53843a961 docs: Remove Doxygen \brief tags. 
Doxygen and the wiki bridge don't need them; they'll both just use the first
line/sentence instead.

Fixes #8446.

c552cc6847 We don't require the audio system to be initialized for audio format conversion 
This is helpful for tools pipelines where audio devices are never used.
