Add Control/State Interfaces.
These interfaces will be used to increase composition
and decrease inheritance in the metadata controls.
ControlDelegates are responsible for getting/setting values,
While ControlOptions are responsible for validating values
(breaking these two apart allows, for example, unused sliders
and unused enums to share the same ControlDelegate, but have different
options, with minimal code duplication).
StateDelegates are for read-only values that may change.
ControlDelegate inherits from this because it will allow
the State interface to be passed around, while one owner
maintains control of updating it behind the scenes.
BUG: 30140438
TEST: unit tests pass. Interfaces only so no new tests
