To try to isolate regressions identified in golden file testing

The thread on which the runner services `CreateApplication` calls is now called `io.flutter.runner.<aot|jit>`. Each application will launch four threads named `<application_name>.<platform|ui|io|gpu>`.

`fx shell ps -T` is an easy way to tell which runners are hosting which applications.

The mobile shells all use the same isolate snapshot. This is also the snapshot used by the service isolate. This works towards a world where the isolate snapshot is no longer a member variable of the DartVM instance. Instead, all snapshots must be specified in the run configuration. For now, the new `Shell::Create` overload will only be used by Fuchsia till I refactor `dart_vm.cc`.

There are no API updates to the mobile shells.

If a line is right justified, then remove any trailing whitespace from the
text range given to Minikin.  Right justification shifts the line's glyphs
by the layout advance computed by Minikin, and this advance should exclude
whitespace so that the last visible character will be flush with the right
margin.

See https://github.com/flutter/flutter/issues/16333

The text skew value is based on Blink's implementation.
