[Site Isolation] Remove dead process-qualified media identifier plumbing
https://bugs.webkit.org/show_bug.cgi?id=321126
rdar://184160039
Reviewed by Charlie Wolfe.
The UI process now pairs a bare WebCore::MediaPlayerClientIdentifier from IPC
with
the process identity of the sending IPC::Connection, so nothing constructs or
sends a
process-qualified media identifier anymore. Delete the two pieces of machinery
that
served only those senders:
- processQualify(), whose last callers were removed when the media manager
messages
and the layer-tree / text-recognition messages were converted.
- The WebKit::PlaybackSessionContextIdentifier serialization alias, whose
generated
coder is now unused and which needlessly advertised the type to
IPC.serializedTypeInfo.
WebKit::PlaybackSessionContextIdentifier itself stays. It remains load-bearing
as
UI-process-internal state — it is how the UI process distinguishes same-numbered
media elements in different processes. The end state is the point: the UI
process
constructs this type and never receives it.
No change in behaviour; pure dead-code removal.
