kselftest/arm64/mte: Preparation for mte store only test
Since ARMv8.9, FEAT_MTE_STORE_ONLY can be used to restrict raise of tag
check fault on store operation only.
This patch is preparation for testing FEAT_MTE_STORE_ONLY
It shouldn't change test result.

kselftest/arm64/mte: Register mte signal handler with SA_EXPOSE_TAGBITS
To test address tag[63:60] and memory tag[59:56] is preserved
when memory tag fault happen, Let mte_register_signal() to register
signal handler with SA_EXPOSE_TAGBITS.

kselftest/arm64: mte: Skip the hugetlb tests if MTE not supported on such mappings
While the kselftest was added at the same time with the kernel support
for MTE on hugetlb mappings, the tests may be run on older kernels. Skip
the tests if PROT_MTE is not supported on MAP_HUGETLB mappings.

kselftest/arm64: mte: Use the correct naming for tag check modes in check_hugetlb_options.c
The architecture doesn't define precise/imprecise MTE tag check modes,
only synchronous and asynchronous. Use the correct naming and also
ensure they match the MTE_{ASYNC,SYNC}_ERR type.
