Makes the following changes to the behavior of precache:
- The --all-platforms flags now fetches all artifacts, rather than just
  turning off platform filtering of selected artifacts.
- Explicitly requested artifacts are no longer subject to platform
  filtering. E.g., 'precache --ios' will download iOS artifacts on
  Windows and Linux (but 'precache' without an 'ios' flag will still
  only download iOS artifacts on macOS).
- Desktop platform artifacts now respect the bypassing of platform
  filtering.

Fixes #53272

Adds a VisualDensity.adaptivePlatformDensity static function that returns different values for visual density based on the defaultTargetPlatform. Returns compact for desktop platforms, and a default visual density for other platforms.

Updates the Windows app template to use the new DartProject API, significantly simplifying the template.

Increments the template version, even though this isn't itself a breaking change, so that users will be prompted to update their projects rather than be broken later when the old API is removed.

This will allow experimenting with the remove to string transformer before we're ready to turn it on by default. This doesn't work for web yet since we use dart2js instead of the frontend_server for producing kernel

* Allow user to specify which Chrome binary to use.
