KVM: selftests: Verify XTILE_DATA in XSTATE isn't affected by IA32_XFD
Add asserts to verify the XSTATE metadata for XTILE_DATA isn't affected
by disabling AMX tile data via IA32_XFD. XFD doesn't intercept XSAVE,
it only prevents setting bits in XCR0, i.e. regardless of XFD, AMX state
is managed by XSAVE/XRSTOR as long as the corresponding bits are set XCR0.
