[X86] Use pseudo instructions to zero registers in `buildClearRegister` (#163358)
In `buildClearRegister` use the correct pseudo-opcode for each register
class:
- For `VR128`, use `V_SET0`
- For `VR256`, use `AVX_SET0`
- For `VR512`, use `AVX512_512_SET0`
- For `VK*`, use `KSET0Q/KSET0W`
This avoids illegal register/opcode pairings and machine verifier errors
when clearing call-used registers under `-fzero-call-used-regs=used`.
Fixes: #163053
