Pieter De Baets d42ccca2e1 Allow native modules to customize the main-thread init behaviour
Summary:
We've simplified a lot of the conditions for eager of the module init so now we can introduce a final switch to allow modules to opt-out (and in the future opt-in if they still require the behaviour).

We now require you to be explicit about the intended behaviour and implement the `+ (BOOL)requiresMainQueueSetup` method on your module. When you return YES from this method, it tells the bridge the module needs to be created on the main thread (and to avoid deadlocks, we do so eagerly during bridge startup). When you return NO, the native module will be initialised when it's first accessed from JS.

The current behaviour is maintained but a warning is emitted until the new API is adopted.
