Ported from Topaz

This adds an isFocusable to SemanticsFlag so that the framework can tell the engine what semantics nodes are allowed to be focused, which will affect what platform flags are applied to the semantics information.

This flag is not yet in use by the frame

This reverts commit fcc4ab32.

Fixes https://github.com/flutter/flutter/issues/41394 and other
related correctness issues.

TBR: @arbreng @jason-simmons @mehmetf 

Started asserting the FlutterEngine is running before communicating
over channels.  This changes a null pointer exception to an
NSException that will provide some meaningful data to clients
incorrectly using the engine in an add-to-app situations.

Split out the logic to handle status bar touches into its own function.  This should make add-to-app clients' lives easier.
