Populate field trial registry

The lists has been constructed by grepping the code base from commit
bfc2a3553d56 ("Remove more codec-related templating") using the PCRE
'(?<=")WebRTC-[^\s/"]+' and manually removing some false positives. Each
field trials has then, on a best effort basis, been associated with a
bug by doing a reverse git log lookup and using the corresponding bug
tag that was associated with the commit where the field trial key was
first introduced.

The field trials are divided into active and policy exempt. The latter
are for field trials that were added before commit c4a35898d916 ("Add
documentation for field trials") which introduced the new policy that
field trials henceforth needs to be registered. These field trials may
not have an associated bug nor an end date.

For all field trials that have been deemed experimentational, including
many policy exempt ones, an initial end date of 2024-04-01 has been
chosen. This date was chosen based on that the policy was introduced on
2022-06-23 and will give about 6 month grace period to allow cleanup of
potentially already expired field trials. Owners are of course free to
adjust the end date at a later time.

The lists have been validated by running most tests with the following
GN arg set:

rtc_strict_field_trials = "dcheck"
