Subject: [PATCH] feat(select): close select programatically

* implement ability to close select programmatically

* refactor(select): made changes based on PR feedback, namely assigning overlay to the overlay property at then end of the open function, applying DeMorgan's Law to a condition, and returning the overlay dismiss promise from the close function

* refactor(select): made additional changes to closing select component programmatically to resolve issue 11318
