[PATCH] MdeModulePkg/Mem: Memory paging related attributes must be separated from others

[Malgorzata Kukiello <jacek.kukiello@intel.com>]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2982

During a recent change (bda18f5ed04f5317ab2bdc9da4530c078b33cc63) that changed
the way memory attributes are handled it affected a function in Page.c that
would clear all memory attributes even security related ones
