Relocate shared EventEngine APIs (#28721)
Partially collapse `event_engine_factory.cc` into `event_engine.cc`. Add a new function `DefaultEventEngineFactory` which is used to set a default event engine factory at link time, separate from the factory that can be set at run time. Implemenet this function in `default_event_engine_factory.cc`. This allows alternative default event engine factories to be implemented without requiring the duplication of the implementations of `SetDefaultEventEngineFactory`, `CreateEventEngine`, and `GetDefaultEventEngine`.pull/28738/head
