In a session, we should try to get a measure of:
- Whether the cache was:
- Non-existent
- Valid and loaded
- Corrupt and discarded
- Late and ignored
- Time spent constructing the cached document in the child
- How long it takes to paint about:home at startup when the cache is enabled and valid

This doesn't include tests for the CACHE_RESULT_SCALARS.CORRUPT and
CACHE_RESULT_SCALARS.LATE cases. Those tests will be added in
bug 1633051.

I have verified that the browser.startup.abouthome_cache_result scalar is collected and viewable in about:telemetry on the Firefox RC 80 (beta channel, BuildID 20200818235255), the latest Firefox Beta 81.0b1 (BuildID 20200824150741), and the latest Nightly 82.0a1 (BuildID 20200824215021) using Windows 10 x64, macOS 10.15.4, and Linux MX 4.19.
@mconley, please let me know if this verification was insufficient.
