MdeModulePkg: disable properties table generation but retain the code

Browse Source 
This is the minimal change required to stop exposing the EFI properties
table, which is deprecated. Given how the implementation is entangled
with the code that exposes the related memory attributes table, most of
the code is retained, and further cleanups are relegated to subsequent
patches.
