  -----------
  [NFC][AMDGPU] Add cost tests for narrow integer to fp casts (#225341)

Covers integer sources from a byte to 31 bits converted to half, float,
bfloat and double, as vector lanes and as scalars, over the subtarget
combinations that change the expansion. The existing cast tests get the
same subtarget coverage and the cases they were missing. The costs
recorded here are the ones the model reports today.
