SPC Codec: Refactor for CPU and clean up some things.

CPU optimization gets its own files in which to fill-in optimizable
routines.

Some pointless #if 0's for profiling need removal. Those macros are
empty if not profiling.

Force some functions that are undesirable to be force-inlined by the
compiler to be not inlined.

Fix 87021f7 errors. There is no this->echo_pos when SPC_NOECHO != 0.

Anyway, that's true now.

Fix FS#9577 - SNES player missing tracks on certain SPCs

Affected BRR cached waveforms but not realtime BRR decode as far as
I could ascertain. BRR cached waves required loop points to be inside
the initial waveform but this change removes that restriction.

SPC Codec: Need to restore a bit more data from cached waves.

'Nuff said. Last update wasn't quite right.

SPC Codec: Have metadata parser fill in frequency and bitrate.

SPC Codec: Simplify configuration and assume nothing need be disabled.

Most SoCs are these days are fast enough for realtime BRR, gaussian
interpolation and echo processing.

Fix CPU boosting in test_codec.

Boost only for tests and unboost immediately afterwards. It was leaving
the CPU boosted after exiting.

USB: Detect charging-only mode upon cable insert, not host detect.

Letting go of the button before the host is detected allows storage mode
to be entered even though a button was down when plugging. Sometimes the
host would try several times and the button would have to be held down
for several seconds to avoid a storage connection.

The adjustment wasn't made when switching to setup request host
detection.
