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

Browse source

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`.
