[AMDGPU] Fix SIFoldOperandsImpl::canUseImmWithOpSel() for VOP3 packed [B]F16 imms. (#142142)
VOP3 instructions ignore opsel source modifiers, so a constant that
contains two different [B]F16 imms cannot be encoded into instruction
with an src opsel.
E.g. without the fix the following instructions
`s_mov_b32 s0, 0x40003c00 // <half 1.0, half 2.0>`
`v_cvt_scalef32_pk_fp8_f16 v0, s0, v2`
lose `2.0` imm and are folded into
`v_cvt_scalef32_pk_fp8_f16 v1, 1.0, 1.0`
Fixes SWDEV-531672
