AMDGPU: Validate VOPD/VOPD3 physical source registers against operand RC

Replace isVGPR checks with isValidVOPDSrc that validates physical source
registers against the actual combined VOPD/VOPD3 instruction's operand
register classes. Now we also validate operands for VOPD instructions.

Git commit 90bb7c4801ff65aecf4521892436ca54c73bfd8c by Petar Avramovic on 21/07/2026 at 11:26..
AMDGPU: Reland: Codegen for v_dual_dot2acc_f32_f16/bf16 from VOP3

For V_DOT2_F32_F16 and V_DOT2_F32_BF16 add their VOPDName and mark
them with usesCustomInserter which will be used to add pre-RA register
allocation hints to preferably assign dst and src2 to the same physical
register. When the hint is satisfied, canMapVOP3PToVOPD recognises the
instruction as eligible for VOPD pairing by checking if it is VOP2 like:
dst==src2, no source modifiers, no clamp, and src1 is a register.
Mark both instructions as commutable to allow a literal in src1 to be
moved to src0, since VOPD only permits a literal in src0.

Original patch had a bug where it did not check if physical src
registers match register class of appropriate operand in fullVOPD
instructions, check is now done via isValidVOPDSrc.
