Implement CreateInstanceForHandle.

A method on ApplicationManager that allows a process that launches another process to register the launched process with the ApplicationManager. In the Shell, this creates an ApplicationInstance, OutOfProcessNativeRunner and ChildProcessHost. This change makes it possible for a ChildProcessHost to be created for an existing process rather than one it must launch.

I think in a future CL I should refactor this class more to make the difference between the type the shell starts and the type someone else starts a bit clearer. Currently it just triggers on whether or not app_path_ is empty which I think is a bit brittle.

Adds an apptest for this that:
- exposes a service from the apptest
- apptest starts a native exe ("driver") via the shell
- native exe ("driver") starts another native exe ("target") via base::LaunchProcess
- driver creates platform channel and passes one side to target and the other side to the shell via CreateInstanceForHandle
- target connects to service exposed by the apptest.
