maxIntrinsicWidth is the sum of the width of all lines in the input
(if the width were any smaller, the renderer might have to wrap a line)

minIntrinsicWidth is the maximum width of a word (if the paragraph were
any narrower, the renderer would have to truncate a word)

It was accidently removed in a5e26f1f.

This is for Fuchsia where we would like it to be located at //third_party/flutter.

This registers a test font manager that maps all fonts to the Ahem font

Fixes https://github.com/flutter/flutter/issues/12513

They help the analysis service identify packages and are now mandatory on Fuchsia.

LayerBuilder

This was used by AndroidSurfaceSoftware but is now obsolete

Make sure we await for the file writing to complete before reporting that compilation is done. (#4210)

For each line, Layout scans for word boundaries and adds extra space between
words if the line is justified.

Added it to a few targets.

This reverts commit d43d3534.

Clear regression to the flutter_gallery_ios__transition_perf benchmarks:
  * average_frame_build_time_millis: 1.4x
  * missed_frame_build_budget_count: 1.2x

No regression seen for other iOS benchmarks (e.g. scrolling).

* Switch from FlutterFastaTarget to FlutterTarget as FlutterFastaTarget was removed.
