This creates a custom dartdoc tool that will generate snippet blocks in our API docs that allow the user to copy easily to the clipboard, and will also embed the snippet code into a template to show it in a larger context with an app.

This PR adds the snippet tool, a template, and a couple of HTML skeleton files, one for snippets that are designed to be in an application setting, and one where it simply puts a nice container around existing snippets, making them easier to copy to the clipboard.

This reverts commit 93573de2.

Fails in the devicelab:

```
run:stderr: A problem occurred evaluating project ':app'.
run:stderr: > Could not resolve all files for configuration 'classpath'.2018-10-23T10:46:46.335864:

Ensure that cached dill files for builds with --track-widget-creation
always have .track. in the file name to avoid mixing transformed and
untransformed kernel files.

Adds an integration devicelab test that runs an Android app with two
custom named isolates. Tests that the isolate names are present and that
it's possible to attach to just one of the isolates.

Fixes flutter/flutter#22009
