Most are brought over straightforwardly, their Telemetry callsites reworded
to use Glean, with mirroring to the Telemetry probes taken care of by the Glean
Interface For Firefox Telemetry (see the telemetry_mirror property).

There was only one special case:

• PERF_DOM_CONTENT_LOADED_FROM_RESPONSESTART_MS doesn't exist.
  As such neither it nor performance.pageload.dcl_responsestart ever reported
  data.
  So we removed them to tidy it away.
  (PERF_DOM_CONTENT_LOADED_TIME_FROM_RESPONSESTART_MS remains unchanged.)
• PERF_DOM_CONTENT_LOADED_MS doesn't exist.
  However, I'd already mistakenly read it as PERF_DOM_CONTENT_LOADED_TIME_MS,
  and successfully migrated it for performance.pageload.dcl, so it gets a pass.

None of DESERIALIZE_{BYTES|ITEMS|US} were enabled to be collected in
geckoview mode, so they never reported data.
