BaseTools/GenFw: Enhance GenFw to support PRM GCC build
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3802 Since PRM module needs to support export table in PE-COFF, we'll enhance GenFw tool to support this. Add one export flag in GenFw tool. If export flag is set: Step1: Scan ELF symbol table based on PRM module descriptor to get descriptor offset address; Step2: Find PRM handlers number and name in COFF file based on the address from step1; Step3: Write PRM info such as handler name and export RVA into COFF export table. PRM option currently only supports DXE RUNTIME driver and X64 arch.
