i386: Disable SImode/DImode moves from/to mask regs without avx512bw [PR118067]

SImode and DImode moves from/to mask registers are valid only with AVX512BW,
so mark relevant alternatives in *movsi_internal and *movdi_internal as such.

PR target/118067

gcc/ChangeLog:

* config/i386/i386.md (*movdi_internal):
Disable alternatives from/to mask registers without AVX512BW.
(*movsi_internal): Ditto.
