Henrik RydgårdandClaude Opus 5 333d84935e Add --force-hle, and stop reporting a normal sceAudiocodec re-init
--disable-hle had no counterpart, which made "is this our fault or the game's?"
awkward to answer: the only ways to put our HLE back were a per-game config or
hiding the firmware, and neither works from a script - the setting is per-game
and the firmware gets found anyway. --force-hle takes the same bitmask and runs
our HLE for those libraries even where the real module is now the default, so
the same repro can be run both ways and the logs diffed.

Used it on the warnings left over in Tekken 6 under the real mpeg.prx. Three of
them appear identically with --force-hle=16, so they are the game's own and
match what the hardware answers: sceKernelChangeThreadPriority(-1) eight times
in a row (pspautotests/threads/threads/change says hardware returns
UNKNOWN_THID for -1 too), sceAtracAddStreamData on a released id with a zero
byte count, and a sceKernelDeleteMutex on a garbage id.

The fourth only happens under the real module and is ours. mpeg.prx sizes its
allocation through a scratch context in its own bss and calls
sceAudiocodecReleaseEDRAM on that one, while decoding through a different
context that never gets released - so the next movie's sceAudiocodecInit finds
a live decoder and replaces it. That is once per video on every game running
the real module, and it was a WARN_LOG_REPORT, so it would have reported from
everyone's machine. It is bounded - removeDecoder deletes the old one and Init
makes exactly one more - so it is an INFO_LOG now.
