No change to logic, just moving some files around.

Both of nonembedded UMA recorder and replayer classes are just used in
a particular place and are not shared (or "common") between webview
code. So This moves them closer to where they are actually used:
- AwNonembeddedUmaRecorder is only used in nonembedded processes so it's
  moved to nonembedded dir.
- AwNonembeddedUmaReplayer is only used in the browser process so it's
  moved alongside the AwMetricsServiceClient.

This should align better with the scope of the current webview
subdirectories structure and help having better OWNERs scope for each
class.
