[infra] Migrate to new analyzer plugins

[dcharkes]

Use the new analysis plugins.

This significantly slows down command-line experience:

$ dart tool/ci.dart --analyze
+dart analyze --fatal-infos pkgs/code_assets pkgs/data_assets pkgs/hooks pkgs/hooks_runner pkgs/json_syntax_generator pkgs/native_analyzer_plugin pkgs/native_test_helpers pkgs/native_toolchain_c pkgs/pub_formats
Analyzing code_assets, data_assets, hooks, hooks_runner, json_syntax_generator, native_analyzer_plugin, native_test_helpers, native_toolchain_c, pub_formats... 0.8s

$ dart tool/ci.dart --analyze
+dart analyze --fatal-infos pkgs/code_assets pkgs/data_assets pkgs/hooks pkgs/hooks_runner pkgs/json_syntax_generator pkgs/native_analyzer_plugin pkgs/native_test_helpers pkgs/native_toolchain_c pkgs/pub_formats
Analyzing code_assets, data_assets, hooks, hooks_runner, json_syntax_generator, native_analyzer_plugin, native_test_helpers, native_toolchain_c, pub_formats... 20.6s

Also, this causes errors in the packages not in the workspace:

• Analyzer plugins are not supported in _inner_ analysis options. sdk#61481 (comment)

Also, there's been a breaking change between the beta release and the latest dev release. So all dev bots fail. Ditto stable is an older version of the analyzer plugin protocol. So all stable bots fail too.

Very cool! Thanks for trying out the new plugins!

Good catch; I think this is the highest priority issue seen here.
