ArmPlatformPkg/Scripts: Infer dll load address from console output

Browse Source 
cmd_load_symbols.py can only load symbols from FV. Add the possibility to
use UEFI console output to calculate dll load address and send
add-symbol-file commands directly to ArmDS debugger

dll load address can't be used directly from UEFI output, see comment in
DebugPeCoffExtraActionLib: "This may not work correctly if you generate
PE/COFF directly as then the Offset would not be required".

1) Use objdump -S module.dll | grep <_ModuleEntryPoint> to get offset
in dll (offset)
2) Use Entrypoint=<address> from UEFI console output (entrypoint)
3) dll load address is (entrypoint)-(offset)
