metrics: add edid version and serial number to DisplayStatus

Initially, the commit 0211765461b3132d491cfc0adb502ff0bcc0e912, which
introduced ExternalDisplayEventsObserver, used InfoData instead of
TelemetryData and was reverted as it was incorrect type of data that was
used.

It was split into smaller pieces - 1) https://crrev.com/c/6563693 2)
https://crrev.com/c/6563694 3) https://crrev.com/c/6543589

Now, ExternalDisplayEventsObserver uses DisplayStatus, which is part of
the TelemetryData, but we need edid version and serial number to be sent
via the Telemetry API for clients to distinguish displays when they
triage problems.

This CL duplicates these two data members to resolve this issue.

PS: usage of these new data fields will be adde in the next CL.
