arch-arm: Add support for Tarmac trace generation

This patch introduces the TarmacTracer: an instruction tracer which
allows to dump a gem5 execution trace in Tarmac format [1]. The new
tracer is supporting either Tarmac and TarmacV8 format specifications.
Not every traceable information has been implemented:

Implemented Trace Type:
    Instruction Trace
    Register Trace
    Processor Memory Access Trace

Unimplemented Trace Type:
    Program Flow Trace
    Event Trace
    Memory Bus Trace
