-------------------
After audio backend migration some android devices screen captures became mute.
Liz instructed to enable openSL ES via some SDL hint.
Found the proper one in https://wiki.libsdl.org/SDL3/SDL_HINT_AUDIO_DRIVER.
Added it restricted to android.

UPDATE:
Got myself wondering how things work on SDL after using that hint, and checked that one must provide a list of drivers "opensles,aaudio,..." to be attempted.
Afraid of some devices failing on openSL ES, and to avoid hand providing entire list, i've added fallback logic so entire SDL's driver list can be tried just in case.
Default list in https://github.com/libsdl-org/SDL/blob/release-3.4.14/src/audio/SDL_audio.c.
