[X86][SSE] LowerVectorAllZeroTest - add support for >256-bit vectors
Reduce by splitting the vector until we reach the target size for PTEST/MOVMSK_PCMPEQ. There might be some cases where AVX512 can perform this with 512-bit vectors but so far I haven't encountered any such pattern that reaches LowerVectorAllZeroTest.
Prep work for D81547
