Chris Bracken c1058b6203 Support overriding perfetto_root_path
As part of merging Flutter's flutter/buildroot and flutter/engine repos,
Flutter is migrating all third-party dependencies from //third_party to
//flutter/third_party.

This change allows consumers of the Dart SDK (notably Flutter), to
override the path of their third_party/perfetto directory by setting
perfetto_root_path in //build_overrides/build.gn. The Dart SDK does
not override perfetto's path, but does override other variables
(perfetto_build_with_embedder) in the equivalent overrides file secondary/build_overrides/build.gn.

TEST=None. Refactor only; no semantic changes.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
