various components: Remove default/stub init_alignment_constants usage

Traditionally audio_stream has failed to initialize its computed
alignment fields, forcing components to do this themselves even when
they don't actually have special alignment requirements.

Remove all the code that was merely setting default values, leaving
only a handful of spots with special equirements (e.g. eq/aria need to
treat pairs of samples, a few others have HiFi-optimized variants
which need SIMD alignment).
