feat: add warn.redundantExpose for redundant @[expose]/@[no_expose] attributes (#13359) 
This PR adds a `linter.redundantExpose` option (default `true`) that
warns when `@[expose]` or `@[no_expose]` attributes have no effect:

- `@[expose]` on `abbrev` (always exposed) or non-Prop `instance`
(always exposed)
- `@[expose]` on a `def` inside an `@[expose] section` (already exposed
by the section)
- `@[expose]`/`@[no_expose]` in a non-`module` file (no module system)
- `@[no_expose]` on a declaration that wouldn't be exposed by default
