CRAS: mix: Rename cras_mix_add_stride_* to cras_mix_add_scale_stride_*
Let cras_mix_add_scale_stride_* scale the samples from src if needed.
Let cras_audio_area_copy pass 1.0f for now. It will pass a scaler for
gain when software gain is needed in the future patch.
Refactor the unittest to test more scalers on cras_mix_add_scale_stride.

CRAS: mixer - separate out mixer operations for SIMD support
Separate out the mixer operations to a new file. This new file will export
SIMD optimised functions to the existing mixer public API for each SIMD
level compiled.
Build SIMD mixer operations and link to mixer.
Builds the mixer_ops.c once for each SIMD level and exports optimised
function via a uniquely named operations structure.
Check CPU SIMD capabilities during server init.
Initialise the mixer based on CPU capabilities.
