[SelectionDAG] Fix CLMULR/CLMULH expansion (#183537) ...

For v8i8 on AArch64, `expandCLMUL` picked the zext path (ExtVT=v8i16) since ZERO_EXTEND/SRL were legal, but CLMUL on v8i16 is not, resulting in a bit-by-bit expansion (~42 insns). Prefer the bitreverse path when CLMUL is legal on VT but not ExtVT.

v8i8 CLMULR: 42 → 4 instructions.

Fixes #182780
