[HOLD for payment 2023-12-20] [DISTANCE] LOW: PHASE 1: Wave 5 CLEANUP Refactor navigation among screens related to money request features

Remove deep-linking support for screens related to money request

In the current code, deep linking to the screen for each step of money request flow is allowed.

There are logics to handle deep linking to a screen that corresponds to a step in the middle of the money request flow. These logics are not scalable and adds additional complexity.

Let's remove the support for deep linking. All screens should be under a single URL and all steps should be completed under that URL.

We had some more discussion about this in https://expensify.slack.com/archives/C05DWUDHVK7/p1694542449982949 and I believe we should actually double-down on the URL based navigation. It has lots of benefits with the navigation flow (back buttons, screen animations, etc.).

Yes, it is pretty flawed and difficult to understand in its current state. I wouldn't mind taking this issue and having a go at cleaning this up so that it's more predictable and easier to use.

Two big pieces for this were merged today. I'll keep working on cleanup.

Note to self: Try to remove ONYXKEYS.IOU
