Script to summarize CI test results across all device profiles

[tobine]

Currently there are a number of tests (10ish) that are skipped on all device profiles in CI. The current giant scrawl of results across 7 device profiles makes it difficult to recognize gaps like this.
To simplify test result analysis, I'm recommending adding a script that will parse the results across all device profiles and then print a summary for each test that tells how many times it passed and how many times that it had unexpected errors. If there are tests that don't run at all, this script should flag them.
Once all tests are running, any test that's added that doesn't hit any device profiles should cause a CI fail. Such tests should either be updated so that they correctly run on at least one profile, or a profile should be modified so that it will cause the test to be run.
