This removes TextRange from the framework and moves it to the engine, in preparation for using it to return text ranges from the text extent APIs, like Paragraph.getWordBoundary instead of a List<int>.

Also added new tests for TextRange.

The earlier assumption was that the render target would be re-materialized per frame. The render target needs its own picture recorder to be create per frame as well. When render targets are cached in the registry, an existing target will be reused. But submitting the previous frame would have discarded the recorder already. The layer tree paint would then attempt to dererence a null canvas causing a crash at runtime.

Added tests to ensure that this does not happen both with and without a custom compositor specified by the embedder. I am going to rework this code so that the external view embedders thinks of render target access on a per frame basis but that is a larger change. This smaller patchset should unblock broken builds.

dart-lang/sdk@46ae3e4e7a [vm] not remove port if socket was listening by other isolates

Add fml_tests target for the fml unit tests on Fuchsia

This reverts commit 1bfb928e.

Ensure that the device pixel ratio is taken into account with window metrics in physical pixels. (#13708)

This was originally patched in https://github.com/flutter/engine/pull/13193 but
the unit-tests were written under the mistaken assumption (that has been
documented already) that the Flutter window metrics used logical pixel
coordinates. That mistake has been corrected and additional tests to verify
rendering intent has been added.
