We were sending the toolType values as-is which is wrong, e.g touch
events showed in Flutter as mouse events.

The whole process is less than 5 minutes using a 24-CPU GCE instance.

I may further improve it by using containers and more CPUs in the following PRs.

Was previously calling onTouchEvent directly which doesn't make the
event go through the full pipeline (e.g onInterceptTouchEvent is not
called).

* Rename clip mode to clip behavior

So we're consistent across flutter/flutter and flutter/engine

* Clang format

When the FlutterView's window loses focus Flutter cannot bring up the
keyboard (so e.g tapping on text fields doesn't work).

This workaround makes sure that Flutter text fields are working but
unfortunately now the embedded Android view cannot bring up the keyboard
as it's window is not focused.

Submitting this until as a stop gap while we're trying to figure out if
it's possible to allow both windows to bring up the keyboard.
