[CRD iOS] Properly handle in-session connection failures

* Makes ChromotingSession automatically release its resources when the
  connection is closed or dropped remotely, so that scheduled tasks
  don't crash the app.
* Makes ConnectionViewController pop out the host view and reveal the
  error message when the connection is dropped.

Ping?

Sorry yuweih@. Please can you provide the rational as to why this should be merged in M64? What is the risk associated with this CL?

This CL fixes a bug that the Chrome Remote Desktop iOS app occasionally crashes when bringing the app back to the foreground.

The risk is generally low:
* Changes are all within the Chrome Remote Desktop iOS project. It doesn't affect Chrome or anything else.
* The change has been well tested on ToT and we have not found any issue so far.
* The only possible impact could be build failure or other issues on the beta buildbots. If this happens we will be happy to revert the change and target it to M65.

Merge approved! Please make sure to verify the fix after merging it.

Thanks!
