Rather than running the runloop forever, have the API expose an incremental runloop. This allows clients to do other processing if they need it.

This allows for removing the odd construction of having knowledge of GTK event handling built into the library even though nothing in the library uses it; instead runner applications that use GTK plugins (such as FDE's testbed) can do that processing at the application level instead.

This is out of date.

Adds initial use of App.framework in the macOS project configuration,
using that rather than the main bundle as the default Dart bundle, and
expecting flutter_resources to be located there.

This is an incremental step toward aligning with the behvaior of the iOS
version of this class.

change_install_name.py was operating on framework library files
in-place, which breaks GN's timestamp analysis handling since a file
can't be both an input and output of an action. As a result no-op builds
on macOS were not actually no-ops.

This changes the script to operate on an output copy, both fixing the
no-op build issue, and simplifying the GN framework construction scripts
by combining the copy step and the install-name step.
