MdeModulePkg-DxeCore: rename CoreGetMemoryMapPropertiesTable

This patches rename CoreGetMemoryMapPropertiesTable to
CoreGetMemoryMapWithSeparatedImageSection.

The reason is that CoreGetMemoryMapPropertiesTable is called
by MemoryAttributesTable.c to get separated PE image section
information.

It is confusing to use *PropertiesTable, because it is NOT
related to PropertiesTable.c

We rename it to avoid confusing.
