ART: Move functions that can be reused in other benchmark

scripts to utils file

This change moves some functions that can be reused by
other benchmark-related scripts (for example compile
statistics) to the file utils_benchmark.sh to make
work on future patches easier.

Test: ./scripts/benchmarks/benchmarks_run_target.sh
SystemArrayCopy --iterations 2 --mode 64 --skip-build and
./scripts/benchmarks/test-art-target.sh --default --skip-build
