FED-4507 Analyzer plugin: fix in Dart 3, support analyzer 6.x

[greglittlefield-wf]

Motivation

In newer versions of Dart, analyzer plugins get AOT-compiled, which currently results in the following errors when attempting to launch the plugin:

An error occurred while executing an analyzer plugin: Failed to compile "/home/runner/.dartServer/.plugin_manager/2de6244a0f824110faf7b6fcb3ecc49f/analyzer_plugin/bin/plugin.dart" to an AOT snapshot.
  pluginFolder = /home/runner/.dartServer/.plugin_manager/2de6244a0f824110faf7b6fcb3ecc49f/analyzer_plugin
  exitCode = 254
  stdout = 
  stderr = error: import of dart:mirrors is not supported in the current Dart runtime
Error: AOT compilation failed
Bad state: Generating AOT snapshot failed!


#0      PluginManager._compileAsAot (package:analysis_server/src/plugin/plugin_manager.dart:731)
...

The source of the problem is the use of dart:mirrors.

Changes

• Update over_react annotation instantiation logic (also used by analyzer plugin) to not use dart:mirrors
  • Move dart:mirrors usages in analyzer plugins's documentation tooling out of lib/ and the import graph of the main analyzer plugin, and into tool/
  • Clean up unused code, outdated tests
  • Don't add additional test coverage; annotation parsing and handling is handled by existing tests
• Reorganize analyzer plugin doc generation code using dart:mirrors to live under tool instead of lib
  • It was in lib when it didn't need to be, and was in files that were getting AOT -compiled
• Allow analyzer 6.x, fix
  • The plugin is quite behind on analyzer versions, and I noticed that allowing 6.x is trivial. I rolled that into this PR since it wasn't much more changes, and the QA steps are the same: passing CI, working analyzer plugin in Dart 3
