selftests/x86/amx: Add a ptrace test

Browse source

commit 62faca1ca1 upstream.

Include a test case to validate the XTILEDATA injection to the target.

Also, it ensures the kernel's ability to copy states between different
XSAVE formats.

Refactor the memcmp() code to be usable for the state validation.
