When UefiRuntimeLib links to a DXE driver, its constructor
still registers a Virtual Address Change event. The event callback
will get called when RT.SetVirtualAddressMap() is called from OS.
But when the driver is a DXE driver, the memory occupied by the
callback function might be zeroed or used by OS since the BS type
memory is free memory when entering to RT phase.
The patch reverts commit 97511979b4
"MdePkg/UefiRuntimeLib: Support more module types."
It makes sure that DXE driver cannot link to this library.
