Replace typeid-based dispatch with enum-based dispatch

- Add `Groupped` trait and `member_id` to `AnyOutput`
- Add generic parameter `G` to `Dispatcher`, `Chain`, `Program` etc
- Remove `hint` module and its marker types
- Update macros to support explicit group specification
- Add `gen_program` macro for generating enum-based programs
- Add `GroupProcess` marker type for type-level grouping
