rust_binder: Update looper_flags bitmaps to use kernel::impl_flags!

Thread looper states are currently represented as raw integers and
manipulated via bitwise operations. This lacks type safety, making it
possible to mix up different flag types without compile-time warnings.

Use kernel::impl_flags! to migrate looper_flags to a strongly-typed
bitmask, enforcing compile-time safety.

Key changes:
- Define `LooperFlags(u32)` and `LooperFlag` enum with 7 variants.
- Change `InnerThread.looper_flags` type to `LooperFlags`.
- Update looper state transitions and checks to use type-safe methods.
- Convert `looper_flags` to `u32` for hex formatting in `debug_print`.
