tools/power turbostat: Add selftests for SMI, APERF and MPERF counters

The test requests BICs that are dependent on SMI, APERF and MPERF
counters and checks if the columns show up in the output and the
turbostat doesn't crash. Read the counters in both --no-msr
and --no-perf mode.

The test skips counters that are not present or user does not have
permissions to read. It is not an error, but the test may not be as
exhaustive.
