Move snippets package back into flutter repo (#147690)
## Description

This moves the snippets package back into the Flutter repo so that API documentation generation can happen without the use of `dart pub global run` because `pub run` doesn't handle concurrency well.

The change modifies the dartdoc building process to include building an executable from the snippets tool and installing that in the cache directory for use during docs generation.

The snippets tool will reside in dev/snippets, where it originally resided before being moved to https://github.com/flutter/assets-for-api-docs.

The snippets code itself is unchanged from the code that is in https://github.com/flutter/assets-for-api-docs/packages/snippets.

This directory contains tools and resources that the Flutter team uses during the development of the framework. The tools in this directory should not be necessary for developing Flutter applications, though of course, they may be interesting if you are curious.

The tests in this directory are run in the framework_tests_misc-* shards.
