amadeus: Fixes and initial 15.0.0 support (#3908)
* amadeus: Allow OOB read of GC-ADPCM coefficients

Fixes "Ninja Gaiden Sigma 2" and possibly "NINJA GAIDEN 3: Razor's Edge"

* amadeus: Fix wrong variable usage in delay effect

We should transform the delay line values, not the input.

* amadeus: Update GroupedBiquadFilterCommand documentation

* amadeus: Simplify PoolMapper alignment checks

* amadeus: Update Surround delay effect matrix to REV11

* amadeus: Add drop parameter support and use 32 bits integers for estimate time

Also implement accurate ExecuteAudioRendererRendering stub.
