Partial Screen Sharing: Task Switcher - Dagger Module and Core Startable

Implement the wiring to start the task switcher triggering:
- Creates the dagger module that binds the repo implementations.
  Currently binds the no-op implementation of the
  MediaProjectionRepository
- Add the core startable to the sysui module
