[Android] SelectPopupDialog - resolve style for <select> dialogs.

Right now the <select> dialogs use directly
R.layout.select_dialog_(multi|single)choice defined in the Android
framework. Adding an extra level of indirection to them through attrs
since other builds need to override these two layouts.
