kselftest/arm64: Verify all different mmap MTE options
This testcase checks the different unsupported/supported options for mmap
if used with PROT_MTE memory protection flag. These checks are,
* Either pstate.tco enable or prctl PR_MTE_TCF_NONE option should not cause
any tag mismatch faults.
* Different combinations of anonymous/file memory mmap, mprotect,
sync/async error mode and private/shared mappings should work.
* mprotect should not be able to clear the PROT_MTE page property.
