maxIntrinsicWidth represents the width of the paragraph if no word wrap is
applied. This can be calculated by summing the width of all runs within each
block of text delimited by a hard line break. maxIntrinsicWidth is the
maximum width among the blocks in the paragraph.
Fixes https://github.com/flutter/flutter/issues/21965
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.
