amadeus: Update to REV11 (#3230)
This should implement all ABI changes from REV11 on 14.0.0

As Nintendo changed the channel disposition for "legacy" effects (Delay, Reverb and Reverb 3D) to match the standard channel mapping, I took the liberty to just remap to the old disposition for now.
The proper changes will be handled at a later date with a complete rewriting of those 3 effects to be more readable (see https://github.com/Ryujinx/Ryujinx/pull/3205 for the first iteration of it).
