x86/x86asm: support AVX instructions

This CL adds support for AVX(1, 2, 512) instructions. A new, XED
data-based decoding path is added. For now, the new code path is
used only for VEX- and EVEX-prefixed instructions.

Test cases are generated from running the assembler tests
(cmd/asm/internal/asm/testdata) in reverse for the Go syntax. For
GNU and Intel syntaxes, the expected strings are extracted from
the system objdump output.

For golang/go#78065.
