Local mutated bookmarks persistence & The new bookmarks persistence

[mohannad-hassan]

Note: Decided to include #685 in this as well, to be able to review the mutations DB and how it's used. This, this and this are the open discussions from there.

Here's the description:
Introduces the repository for the local mutations database of bookmarks. This stores full records, but encapsulates the operation as well.

The backend's logic for bookmarks doesn't allow editing; only creation and removal.

---

This is the new bookmarks persistence that merges the synced DB and the mutations DB. This is intended to be used throughout the app in place of the CoreData persistence.

Not addressed in this PR:

• How to handle the lifetime before the user connects the device to the Quran.com account.
• Migrations.

I may handle the first point in this PR, but most likely I plan to separate it into a separate PR.
