Henrik RydgårdandClaude Opus 5.5 4ba981b5b3 sceAtrac: Charge setting data and decoding what the ME takes

Setting data decodes and throws away the frames before the first sample,
so on hardware it costs a decoder setup plus that decode, with the caller
waiting: ~900us for mono Atrac3 and ~3.5ms for stereo Atrac3+, whatever the
buffer size (pspautotests threads/scheduling/callcosts). It was charged
100us.

Decoding a frame now costs what the same frame costs through
sceAudiocodecDecode, through the shared ME queue, instead of a flat
2300us. That's about the same for stereo Atrac3+ and less for Atrac3
(685us mono, ~1100us stereo). The first Atrac3+ frames after setup still
come out ~500us short.
