perf test: Add arm64 asm pureloop test shell script
Add a script to drive the asm pureloop test for arm64/CoreSight that
gathers data so it passes a minimum bar for amount and quality of
content that we extract from the kernel's perf support.
Committer notes:
Add the install of tests/shell/coresight/*.sh to
tools/perf/Makefile.perf as we're starting to populate that dir.
