Summary: - Add `key` field to `SemanticsNode`, while moving key into `foundation` library so it can be used by the render layer. - Introduce `SemanticsProperties` and move many of the `Semantics` fields into it. - Introduce `CustomPaintSemantics` - a `SemanticsNode` prototype created by `CustomPainter`. - Introduce `semanticsBuilder` and `shouldRebuildSemantics` in `CustomerPainter` **Breaking change** The default `Semantics` constructor becomes non-const (due to https://github.com/dart-lang/sdk/issues/20962). However, a new `const Semantics.fromProperties` is added that still allowed creating constant `Semantics` widgets ([mailing list announcement](https://groups.google.com/forum/#!topic/flutter-dev/KQXBl2_1sws)). Fixes https://github.com/flutter/flutter/issues/11791 Fixes https://github.com/flutter/flutter/issues/1666
