[PATCH 1/4][PR target/88808]Enable bitwise operator for AVX512 masks.

Hi: First, since avx512 masks involve both vector isa and general part, so i add both maintainers to the maillist. I'm doing this in 4 steps: 1 - Add cost model for operation of mask registers. 2 - Introduce new cover class INT_MASK_REGS, this will enable direct move between gpr and mask
