inputgen: bind tizen_input_device_manager, wl_seat only when inputgen APIs is invoked

Separates the input-related interfaces (tizen_input_device_manager, wl_seat) from
other interfaces since these are solely required for inputgen APIs and sends
their events (e.g.,device_add/remove & capabilities) necessitating dispatching.

The 'tizen_input_device_manager' interface provides events to clients binding 'wl_seat'.
Therefore, the efl-util input generator needs to bind 'wl_seat'.
For instance, efl-util may not receive max_touch_count events, leading to
inability to generate touch events.
