[native] Rename InviteLinksContext and InviteLinksContextProvider to DeepLinksContext and DeepLinksContextProvider
To make the context more generalized in preparation for unifying the invite link handling and qr code link handling, renaming it to DeepLinksContext and DeepLinksContextProvider made the most sense to me.
This is not part of a monthly goal, just a follow-up task.
Depends on D9026
Part of ENG-4810
Test Plan: Confirmed all invite links worked as before and made sure that scanning the QR code to log in opened the app and navigated to the scanner
