When a session is cloned, OnStop isn't called and thus
process descriptor doesn't have process type if it was set
after the tracing session started.
This brings back logic similar to https://chromium-review.googlesource.com/c/chromium/src/+/6163823
with a few difference:
- process type is updated (whereas only the process name was previously set)
- The descriptor is written by TrackNameRecorder
- process labels are kept and emitted in TrackNameRecorder
