PPSA15552 passes matching front/up after a listener move; pick a perpendicular up hint instead of throwing so Dead Cells can keep running.
Co-authored-by: Cursor <cursoragent@cursor.com>
Implement sceNgs2GeomApply, which was previously an unimplemented
throwing stub and was blocking Dead Cells (PPSA15552).
The implementation validates null handles/output addresses and writes a
minimal Ngs2GeomAttribute: pitch_ratio 1.0, source position, source
volume/level maxima, and diagonal channel levels for the source's channel
count. It does not implement source attenuation, distance rolloff, panning
or Doppler.
The export lives in Geom.cpp's internal Ngs2GeomApply and is exposed through
the existing default-visibility wrapper in Voice.cpp. Unimplemented.cpp no
longer defines the stub. A passing test was added to Ngs2Geom.cpp.

Restore world-to-listener matrix construction instead of rejecting
non-default orientation, translation or flags.
- Build an orthonormal row-major matrix from position, orient_front
and orient_up; apply the right-handed axis flip for flag 1.
- Store the negated dotted translation in each matrix row.
- Validate unknown flags, invalid or non-finite input, short
orientation axes, and unrepresentable translation without changing
the output.
- Preserve finite velocity and positive finite sound speed.
- Update NGS2 geometry tests and the libSceNgs2 technical debt note.

Implement sceNgs2GeomResetListenerParam and sceNgs2GeomResetSourceParam,
taken from #1021 and limited to the two reset functions. The Geom
structures get their real layouts. sceNgs2GeomCalcListener and
sceNgs2GeomApply stay unimplemented.
