Flutter-intellij: Auto-gen a run config for imported projects with a `lib/main.dart`

[mit-mit]

Opening projects with no IntelliJ metadata is a lot better with the recent fixes. Code analysis works as expected!

However, the project still has no run config, and adding one is a number of steps, incl. having to know some specific paths. Should we consider always adding a run config if there are none?

Steps to Reproduce

1. Create a new project: flutter create ijtest
2. Delete IJ metadata: cs ijtest; rm ijtest.iml; rm -rf .idea
3. Open project: idea .

-> Project analyses but cannot be run

@devoncarew : is it true that the canonical entry-point will (always) be lib/main.dart? If so, any reason we couldn't auto-generated a run config if that file exists?

[mit-mit]

Some apps might not have that file (for example /examples/layers/ doesn't), but if that file exists it's pretty likely it's the entry point.

[devoncarew]

Auto-generation if lib/main.dart exists sounds good -

Tentatively tagging this for next release
