We need a simple method to test Perf with Arm CoreSight drivers, this
could be used for smoke testing when new patch is coming for perf or
CoreSight drivers, and we also can use the test to confirm if the
CoreSight has been enabled successfully on new platforms.
This patch introduces the shell script test_arm_coresight.sh which is
under the 'pert test' framework. This script provides three testing
scenarios:

Below is detailed usage for it:
# cd $linux/tools/perf -> This is important so can use shell script
# perf test list

70: probe libc's inet_pton & backtrace it with ping
71: Check Arm CoreSight trace data recording and synthesized samples
72: Check open filename arg using perf trace + vfs_getname
73: Zstd perf.data compression/decompression
74: Add vfs_getname probe to get syscall args filenames
75: Use vfs_getname probe to get syscall args filenames
# perf test 71
71: Check Arm CoreSight trace data recording and branch samples: Ok
