LUCENE-9345: Separate MergeSchedulder from IndexWriter (#1451)
This change extracts the methods that are used by MergeScheduler into
a MergeSource interface. This allows IndexWriter to better ensure
locking, hide internal methods and removes the tight coupling between the two
complex classes. This will also improve future testing.

> MergeScheduler is tightly coupled with IndexWriter which causes IW to expose
> unnecessary methods. For instance only the scheduler should call
> IW#getNextMerge() but it's a public method. With some refactorings we can
> nicely separate the two.
