[engine] changes to DlVertices::Builder and Stopwatch visualizer. (#57031)

Collection of changes to DlVertices::Builder and the stopwatch visualizer.

At a high level:

* improve performance of the stopwatch visualizer by pre-allocating storage (and sharing it across both visualizers), lookup up font once, and cache the debug frame rate used. Updates to use Dl types instead of SkTypes.

* Change DlVerticesBuilder to allow storing the bounds and use that in the visualizer, since we already know them. Make FML_CHECKS into dchecks, as the dart:ui vertices will already bounds check correctly - so these should only be necessary for debugging engine changes.

Flutter Engine

Flutter CI Status

Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.

The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.

If you want to run/contribute to Flutter Web engine, more tooling can be found at felt. This is a tool written to make web engine development experience easy.

If you are new to Flutter, then you will find more general information on the Flutter project, including tutorials and samples, on our Web site at Flutter.dev. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.dev.

Flutter is a fully open source project, and we welcome contributions. Information on how to get started can be found at our contributor guide.
