[X86][Costmodel] getReplicationShuffleCost(): implement cost model for 8 bit-wide elements with AVX512VBMI

VBMI introduced VPERMB, so cost-model i8 replication shuffle using it.
Note that we can still model i8 replication shufflle without VBMI,
by promoting to i16/i32. That will be done in follow-ups.
