Michael D Kinney 3980808abf BaseTools/Scripts: KEEP .prmexportdescriptor data sections
Update GCC linker script to always keep .prmexportdescriptor
sections and merge them into the .data section.

The .prmexportdescriptor section is only used by PRM modules
for the PRM Export Descriptor Structure that must be kept
in the final image to support adding the PRM Export
Descriptor Structure and its associated PRM Handlers APIs
to a PE/COFF DLL Export section.
