feat: add onDragStart onDragEnd gesture callbacks

[arekkubaczkowski]

Given the significant interest and numerous requests from the community for this feature, I'm excited to introduce it with this pull request.

resolves #998, #1147

@gorhom I think it's also worth to add a callbacks that run on UI thread to react on the changes without unnecessary rerenders. However I need to think a bit about some intuitive API for that

[arekkubaczkowski]

Additionally I would also consider adding them to some hook so user can interact with it from any place.

@gorhom I would be really grateful for review

Awesome! Can't wait to see it merged. We've been patching this manually for quite some time. Would be nice to see it in the library.

I have no idea, it seems like @gorhom is very busy.

@arekkubaczkowski - I am currently trying to tap into some functionality like this and I believe @gorhom's intent is to use gestureEventsHandlersHook to provide callbacks for handleOnStart, handleOnEnd, handleOnActive.

Am I missing the intent of this PR?
