Current MemoryAttributesTable will be installed on ReadyToBoot event at TPL_NOTIFY level, it maybe incorrect when PcdHiiOsRuntimeSupport = TRUE as HiiDatabaseDxe will have runtime memory allocation for HII OS runtime support on and after ReadyToBoot. The issue was exposed at http://article.gmane.org/gmane.comp.bios.edk2.devel/10125. To make sure the correctness of MemoryAttributesTable, this patch is to enhance MemoryAttributesTable installation to install MemoryAttributesTable on ReadyToBoot event at TPL_CALLBACK - 1 level to make sure it is at the last of ReadyToBoot event, and also hook runtime memory allocation after ReadyToBoot.
