Similar to excluded tests pending tests should not count towards runs or
result in console logging because they are effectively not (fully) run.
This reduces visual noise and helps to get the tests running on GitHub
Actions where non-passed tests will count towards a non-zero exit code.
It fixes#20715.
`failedExpectations` was removed from `suiteStarted` and `specStarted` events.
HtmlReporter and HtmlSpecFilter have been deprecated and removed.
The reporter is used in both the unit and the font tests, so this commit
moves it to the test root folder to more clearly indicate that this is a
shared resource and so the font tests don't have to reach into the unit
tests folder to import it (which improves separation).
