audren: Make use of nodiscard, rework downmixing, release all buffers
Preliminary work for upmixing & general cleanup. Fixes basic issues in games such as Shovel Knight and slightly improves the LEGO games. Upmixing stitll needs to be implemented. Audio levels in a few games will be fixed as we now use the downmix coefficients when possible instead of supplying our own
