[Decor] Split RoundedCornerResDelegate into impl and interface

In order to support a new debug corner res delegate, we should split out
the RoundedCornerResDelegate into an interface + implementation. This
will allow us to create a DebugCornerDelegate that can be reused by the
RoundedCornerDecorProvider without needing to duplicate that class
definition.

Test: RoundedCornerResDelegateTest
