ArmPlatformPkg/PrePi: Moved Exception Vector Table to ArmPkg/DebugAgentBaseLib

Browse Source 
In case a DebugAgent library is supported for a specific debugger, we would
expect the exception be caught by DebugAgentLib.
The DebugAgentBaseLib exposes the cause of the exception to the user in the
Serial Terminal.
