Skia should already have such optimizations based on a much more
accurate clip stack. As we move to the retained rendering, SceneBuilder
would be much harder to maintain such cull_rects_ stack so let's just
remove them.
No significant performance change is measured locally on Moto G4 with
flutter_gallery transition perf test and complex_layout scroll perf
test.

```
* Update license
The `dart_vm_entry_points.txt` file is now deprecated in favor of annotations.
Support for parsing and generating the entry-points files will be removed from Dart shortly.
This essentially reverts https://github.com/flutter/engine/pull/4197/
as no one is (or soon will be) implementing an alternative LayerBuilder.
Let's just put everything in SceneBuilder to reduce the YAGNI
(you aren't gonna need it) smell. This will also make retained rendering
API changes much easier.
- Switch core snapshot to Dart 2 and remove support for loading platform.dill.
- Remove support for loading script snapshots.
- Remove support for loading source.
- Remove settings and fix names to reflect the above.
- Remove support for loading the service isolate from source.

* Address source format error.
The behavior of acquire+release annotation handling has changed in
https://reviews.llvm.org/D49355 which breaks the build with the new
Clang. However, as has been pointed out, the acquire+release isn't
the right way to prevent double locking as the annotations negate
each other; the correct way is to use excludes or negative requires.
Using excludes annotations also requires using std::lock_guard instead
of std::unique_lock because the latter doesn't have the thread
annotations due to deferred locking which is not needed in Flutter and
so std::lock_guard is a sufficient alternative.
Instead, send them with the new unknown PointerDeviceKind.
We hit this when running `adb shell input tap` in tests which sends events with
an unknown tool type.
This also fills in a missing conversion for TOOL_TYPE_ERASER.
This fixes issue with compilation trace buffer getting released upon return from VM code to Dart code, before it gets change to save to a file in natives.dart saveCompilationTrace().
