Add target description for avx-avx512.

Add a dedicated target description for the feature combination
avx-avx512 as implemented by certain IA CPU models.

The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared
the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers
displayed as undefined on CPUs that only implemented
X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue.

This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is
replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode.
