This is the first step in a two-step process of moving the package preparation step from a recipe in chrome_infra to a dart script in the flutter repo. This will make it easier to make changes to the process. The second step is to change the infra recipe to call this script.
In addition, I added a step to the packaging process to run flutter create for each type of template so that any pub dependencies of the templates get added to the cache that gets packaged (and thus users can run flutter create --offline and have it work).
Note that the actual packaging into a "tar" or "zip" file now happens here, so a developer could actually run this script on their machine to create a package.
The purpose of this PR is to make it so that when the user runs 'flutter', if they have a .pub-cache directory in their flutter root, we use that instead of the default location for the pub cache. Otherwise, it should act as before.
The eventual goal is to support a pre-populated flutter .zip/.tar.gz file that has everything the developer needs in one bundle. In order for that to actually work, we need to have the pub cache be self-contained, and not in the user's home dir.
Another advantage of this is that if you have multiple flutter repos that you're switching between, then the versions in the pub cache will remain static when you switch between them.
This is an attempt to re-land: #13248. Includes a fix for the test that makes it work on bots in the presence of PUB_CACHE being set, and no other changes.
* Revert "Add tests."

* Revert "Use .pub-cache from Flutter root, if it exists. (#13248)"
This reverts commit 72d6bcc3f7.

In particular, if stdout.supportsAnsiEscapes is false, don't output ANSI.
Also, output stdout/stderr of tests that are normally silenced, if they fail.
Also, update the output to be more convenient when debugging.
Also, expand some abbreviations.
* disables all `flutter test` and `flutter drive` tests on Windows as those two commands are not fully implemented on Windows yet
* fixes other failures on Windows
