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.

## Publish PropertiesTable or not.
#
# If this PCD is TRUE, DxeCore publishs PropertiesTable.
# DxeCore evaluates if all runtime drivers has 4K aligned PE sections. If all
# PE sections in runtime drivers are 4K aligned, DxeCore sets BIT0 in
# PropertiesTable. Or DxeCore clears BIT0 in PropertiesTable.
# If this PCD is FALSE, DxeCore does not publish PropertiesTable.
#
# If PropertiesTable has BIT0 set, DxeCore uses below policy in UEFI memory map:
# 1) Use EfiRuntimeServicesCode for runtime driver PE image code section and
# use EfiRuntimeServicesData for runtime driver PE image header and other section.
# 2) Set EfiRuntimeServicesCode to be EFI_MEMORY_RO.
# 3) Set EfiRuntimeServicesData to be EFI_MEMORY_XP.
# 4) Set EfiMemoryMappedIO and EfiMemoryMappedIOPortSpace to be EFI_MEMORY_XP.
#
# NOTE: Platform need gurantee this PCD is set correctly. Platform should set
# this PCD to be TURE if and only if all runtime driver has seperated Code/Data
# section. If PE code/data sections are merged, the result is unpredictable.
