[v0.2.0 Refactor] [Type-C] Remove static_cell dependency and improve context handling (#668)

- Removed `static_cell` dependency from Cargo.lock and Cargo.toml in
examples and type-c-service.
- Updated Type-C service methods to accept a reference to
`intrusive_list::IntrusiveList` for better context management.
- Modified various service methods to pass the controllers list where
necessary, ensuring proper context usage.
- Commented out unused code related to power policy channels and service
initialization.
- Adjusted the task closure to work with the updated service structure.
- Enhanced error handling and logging throughout the service methods.
