MdeModulePkg/DxeCore:Clear RT attribute on SetCapabilities.
When gDS->SetMemorySpaceCapabilities() is called,
current DXE core will sync all GCD attributes to memory map
attributes, including RUNTIME attributes.
It is wrong, because RUNTIME attributes should be set for
runtime memory only.
This fix clears the RUNTIME attributes before convert to UEFI
memory map. So that the UEFI memory map is good after
gDS->SetMemorySpaceCapabilities() is called.
