analyzer_testing: Move Spelunker into this package

The Spelunker class is only used by analyzer_testing's
PubPackageResolutionTest class, and by a utility script. So I believe
the best place for this class is in analyzer_testing, for two reasons:

* Would we also move the utility script
  (`pkg/linter/tool/spelunk.dart`)? This is a script that lets you see
  a visual tree of the syntax nodes of a Dart script. It has been
  helpful to people writing lint rules, as it helps you understand how
  you need to walk up or down the tree to check conditions. Therefore,
  it will be at least as helpful to people writing analysis rules in
  analyzer plugins (the primary consumers of PubPackageResolutionTest).
  It doesn't need to live in `bin` (though that's one possibility). It
  can live in `analyzer_testing/tool`.
* Then if the utility script lives in analyzer_testing, and
  PubPackageResolutionTest lives in analyzer_testing, and these are the
  sole consumers of Spelunker, it makes sense to move it into
  analyzer_testing. It does not need to be public API; just live in the
  source code.

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).
