Update IntelliJ template for new projects and existing samples (#7501)

* Disable 'Show Excluded' by default

* Move .iml file inside .idea dir

* Remove pub and build excludions as they are automatically set by the Dart plugin

* Exclude .idea folder (new users will edit it through the IJ UI, not the file)

* Move .iml files into .idea dir to be consistent with template changes

* Add workspace.xml from new template to existing samples

* Update current examples to match template changes for excluding folders

* Add missing flutter.yaml to make sure there are no analysis errors

* Add back .pub and build excludeFolder tags per https://github.com/flutter/flutter-intellij/issues/630#issuecomment-272887230

* Remove workspace.xml from example per review feedback
