Update names to match latest gtest version.

Changes:
- Change the case name to suite to match gtest. Did this both in
- the output and in the code.
- Change the names from PASS to PASSED, FAIL to FAILED.
- Change the "XX tests failed, listed below:" line to remove the
  "failed" word to match gtest. Did this for timeouts and slow too.
  Left it for should have failed because otherwise it's not clear
  what that list of failures mean.
- Some small alignment changes such as moving TIMEOUT over 1 character.
- Updated unit tests for the new output.

Bug: 128120124

Test: Updated unit tests pass.
