[AMDGPU] Restrict packed math FP32 instructions to read only one SGPR per operand on gfx12+ (#152465)
Sec. 4.6.7.1 of the gfx1250 SPG states that if an SGPR is used
as an operand, only one SGPR will be read for both the low and high
operations. As a result, the corresponding bits in `op_sel` and
`op_sel_hi` must be the same when the operand is an SGPR.
