Revert "Allow scrolling all of the password management list mode screen" (#5445)

Task/Issue URL:
https://app.asana.com/0/608920331025315/1209106756565265/f

### Description
Reverts changes made in #5377
as it introduces performance issues on the password management screen
with larger password list sizes. Depending on the device / list size, it
can be crippling performance.

### Steps to test this PR
- [x] install `internal` variant to make the next step easier
- [x] Add 500+ passwords (can be done in `Autofill Dev Settings` screen,
using the **Add a lot of sample logins** button)
- [x] Visit password management screen and verify there isn’t a huge
delay in rendering the password list

For contrast, if you try this on `develop` you will notice a large perf
issue.
