Giacomo Travaglini 4c4615523f configs: Add an example elastic-trace-generating script

The new script will automatically use the newly
defined O3_ARM_v7a_3_Etrace CPU to run a simple SE simulation while
generating elastic trace files.

The script is based on starter_se.py, but contains the following
limitations:

1) No L2 cache as it might affect computational delay calculations
2) Supporting SimpleMemory only with minimal memory latency

There restrictions were imported by the existing elastic trace
generation logic in the common library (collected by grepping
elastic_trace_en) [1][2][3]

Example usage:

build/ARM/gem5.opt configs/example/arm/etrace_se.py \
    --inst-trace-file [INSTRUCTION TRACE] \
    --data-trace-file [DATA TRACE] \
    [WORKLOAD]
