Audio: Set default audio stream align to SOF_FRAME_BYTE_ALIGN

This patch changes the default align from 1 bytes to
SOF_FRAME_BYTE_ALIGN that depends on build architecture. It
defaults to 4 in generic build and to values 8 and 16 for
Hifi3/4 and HiFi5 builds.

A macro is defined for frame count align value 1 with name
SOF_FRAME_COUNT_ALIGN. It can be used instead of numeric value 1.
Modules can use it when there is no specific requirement for
frames count constraint.
