core: enable write-implies-execute-never when applicable
HW may or may not support STCLR "WXN" configuration field.
CFG_HWSUPP_MEM_PERM_WXN reflects this state. AArch64 is assumed to
always support this field.
Enable the "WXN" (and UWXN) bits in STCLR upon configuration directive
CFG_CORE_RWDATA_NOEXEC.
