ArmPkg/DebugAgentSymbolsOnlyLib: Add library to print loaded address of the SEC and PEI_CORE modules

This library that uses the DebugAgentLib interface prints the loaded addresses
of the SEC and PEI_CORE module using PeCoffExtraActionLib.

Note: Because there is no PE loader for these XIP modules, PeCoffExtraActionLib is not invoked.
This library scans the firmware volume to find these modules and calculate their fixup loaded
addresses used to load their symbols in the debugger.
