  AMDGPU: Add dedicated features for wavesize support

Previously we had features for which wavesize is active,
and unstructured checks for which targets support which
wavesize.

One assembler test changes because it was artificially
forcing wave64 on gfx1250 for test simplification, and
the supportsWave32 helper function was buggy.
