De-experimentalize starlark defined *rule class transitions* that *only read native options* and *don't have access to attributes that use select()*.

This necessitates de-experimentalizing the entire transition() function.

Still experimental:
- applying starlark-defined transitions on attributes
- applying starlark-defined transitions on starlark build settings anywhere

Still forbidden:
- reading configured attributes on rule class transitions

Newly forbidden:
- transitioning on native flags that are --experimental_ or --incomptaible_

RELNOTES: None.
