adb: move shell service to a separate file.
Upcoming changes to the shell will require significant additions to
the subprocess code, and it will be cleaner if it's in a separate file.
The only functional change here is a new debug tag specifically for
the shell service. Everything else has been copied exactly as-is in
order to make it easier to determine what's changing in upcoming CLs.
