Currently, toggleable exists independently in the material and cupertino libraries. Cupertino's toggleable is a minimal copy of material's, and so it makes sense to have only one toggleable in the widgets layer. This change makes it easier for cupertino's toggleables (switch, radio, checkbox) to potentially have as many capabilities as material toggleables (for example, resolving in different widget states), thus increasing support for the cupertino library. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [ ] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
