If enabled, NX memory protection feature will mark some types of active memory as NX (non-executable), which includes the first page of the stack. This will overwrite the attributes of the first page of the stack if the stack guard feature is also enabled.
The series will override the attributes setting to the first page of the stack by adding back the 'EFI_MEMORY_RP' attribute when the stack guard feature is enabled.
