Log Message:
syncretro: add games.ini reader for per-cabinet button labels
MAME 2003-Plus reports how many buttons a driver wants but never
sends SET_INPUT_DESCRIPTORS, so the door can learn that a cabinet has
buttons but not what any of them IS. Measured by hand: Battlezone
fires on RetroPad Y, Centipede on B -- there is no rule to infer the
mapping, only games.ini, entered by hand per romset.
Add syncretro_games.[ch]: sr_games_load() reads <dir>/games.ini and
selects the section named by the ROM's basename, sr_games_button_label()
and sr_games_stick2() answer NULL when nothing is recorded, and sr_games_labelled() reports whether any button was labelled at all.
State is cleared unconditionally at the top of sr_games_load(), before
any early return, so a console with no games.ini cannot inherit the
previously loaded cabinet's labels.
Add test_games.c and wire it into the SYNCRETRO_TESTS CMake target;
all seven unit tests still pass. Wiring the labels into the door's
help screen is a later task -- this is a standalone, tested module.
