Implement ValueManager and ValueComposer (#183)
* Fix ValueManager implementation
* Implement ValueComposer
* Add constructor for ValueManager
* Add value-expanders.h to flipper_v2.h set
* Move COPY_COMPOSE body into a .c file
* Add test for ValueManager
* Add destructors for ValueMutex, ValueManager and ValueComposer
* Use destructors in tests
* Move composition logic into perform_compose()
* Add docs for perform_compose()
* Add test for ValueComposer
* Replace atomic_bool with bool as g++ compiler doesn't support C11 atomics
* Add Event type
* Add semaphore support to the local target
* Add test for Event
* Update input records and relevant examples
* Rename Event to AppEvent in the cc1101-workaround example
* Rename Event to AppEvent in the irda example
* Use Event in ValueComposer to wait for update request
* Add perform_compose_internal() function
* fix Event/AppEvent
