Updates the platform shims in dev/manual_tests so that Windows and Linux can be built. I had to update the Windows shims, because I was unable to build a Windows app there.
Also updates the analyze.dart script to report all license issues simultaneously instead of just dying after the first failure.
The only substantive code changes are in dev/bots/analyze.dart and dev/bots/test/analyze_test.dart
Switch document generation to use the snippets package instead of the snippets code in the Flutter repo. In the process, some bugs in sample code analysis have been fixed, and I've fixed some more errors in the samples.
This will allow the snippets package to be developed separately from the Flutter repo, and reduce the code in the Flutter repo.
The snippets code is deleted in this PR.
I also converted some comments in the snippet templates to be regular comments instead of doc comments, because having a doc comment block before the imports causes the Dart import sorter to lose the comment. They should have been regular comments in the first place.
The snippets package resides in the assets-for-api-docs repo.
The sample analysis has also been converted to be run in parallel, and I've bumped the Dartdoc version to 1.0.2.
Python 2 has been end-of-life'd since January 2020, all Python scripts
on which Flutter depends have been migrated to Python 3. This changes
documentation and remaining invocations to explicitly invoke python3.

This fixes how the sample analyzer handles missing_identifier errors. It was looking at the wrong line, and missing an else clause, so it was silently allowing missing_identifier errors to pass.
In addition, this fixes the sample generation so that it uses the correct filename for the output files: it previously was looking for the first line that had a filename, which was meant to indicate a non-generated line. This change adds a new Line.generated constructor for generated lines, so that they can also have the correct filename associated with them.
This adds avoid_dynamic_calls to the list of lints, and fixes all instances where it was violated.
Importantly, this lint is NOT turned on for flutter/packages/test, because those changes are happening in another PR: #84478
This switches the sample analysis code to use package:flutter_lints instead of the flutter repo analysis options, so that they are compatible with a similar change to DartPad.
