The UIDartState is now always owned by the isolate and always freed in
the isolate cleanup callback.
In the isolate shutdown callback, if the isolate being shut down is the
main isolate, the RuntimeController is informed which in turn notifies
the RuntimeHolder and thus the ApplicationControllerImpl. The
ApplicationControllerImpl tears down the whole Flutter application.
This fixes Fuchsia bug: MI4-328
This only operates correctly when the application is killed using the
Kill() method. Flutter applications on Fuchsia currently don't have any
way to shut themselves down, see:

Compute the necessary texture resolution using more accurate scaling
information provided by Mozart scene node metrics events instead of the
device pixel ratio provided by the Mozart view properties (which we
might remove in the future).
This allows us to allocate smaller textures when a Flutter view is
being scaled down.
Rather than receiving an ApplicationEnvironment, we now receive a namespace.
Once we have FIDL2, we can plumb the namespace all the way through to Dart.
Instead of updating to match new HID touchscreen hacks exposed by
magenta, just remove the direct input layer entirely. Mozart all the
time from now on.
This version does not recycle buffers. It is meant only as an initial solution,
and the proper buffer recycling logic has been broken out into a separate change
After this patch, platform messages now take the same path through the system
that semantics data does (on Android). Support on iOS will be in another patch.
This patch prepares us to switch sending semantics information over mojom to
using dart:ui directly. Currently the recorded information is dropped on the
floor, but that will improve in future patches.
After this patch, Flutter apps on Fuchsia can access their asset
bundles. Unlike other platforms, the asset bundles are stored in memory
rather than in the file system.
After this patch, we're able to run spinning_square on Fuchsia. I've
left some TODO comments about some shortcuts I've taken that we'll need
to improve in the future.
This patch should contain all the code we need to run Flutter on
Fuchsia's software framebuffer (without text). I haven't actually tried
running the code, so I'm sure it doesn't work yet.
