This reverts commit 755dbeef.

Update engine for removal of Dart_ReadKernelBinary and refactored build targets.

The Fuchsia bots seem to reference this target to figure out the root_out_directory https://fuchsia.googlesource.com/build/+/master/dart/dart_test.gni#67. Note that the presence of the flutter_tester binary location itself is not depended on. Instead, the target is used to infer the directory containing the flutter_tester after a build.

Patching the //build repository in Fuchsia would mean making the tree red till a //topaz patch lands. To avoid doing this, we add back the missing reference.

This allows applications to start a Flutter engine instance during app startup
and keep it running throughout the app process' lifetime.

FlutterActivity subclasses can override createFlutterNativeView to provide a
preinitialized FlutterNativeView instance and override retainFlutterNativeView
to signal that the FlutterNativeView should be kept alive when the activity
is destroyed.

This removes the Application::Delegate interface and instead uses a closure that captures the task runner. The interface was expected to be more complicated than it turned out to be.

Follows the same pattern followed for termination in response to isolate shutdown.

Instead, keep it around to service more requests. There may be a race between runner shutdown and request for new applications.

Fixes https://github.com/flutter/flutter/issues/17497

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.

Also exclude trailing whitespace from center justified lines.
