Use more-specific types for test results and diagnostics.

[ericsnowcurrently]

(for #14866)

Some of the problems we've run into relate to how we are using the same broad types for all the different kinds of test results (passing, failing, active and unknown). This change addresses that by switching to specific types tailored to the relevant kinds of test results.

Note: I will be updating for eslint once reviews are done.
