Parent issue #13326

This PR

• Adds ScanHistoryListFragment: An instance per view pager tab will be used, ScanHistoryFragment will serve as parent of the ViewPager. I decided not to put the ViewPager into the Activity in order to keep the activity as simple as possible in case we decide to move to a single activity structure.
• Moves Toolbar from ScanHistory Activity to ScanHistoryFragment: Same reasons as above
• Adds ViewPager2 to ScanHistoryFragment
• Adds "lift on scroll" (Z-axis) behavior. I tried adding show/hide on scroll behavior but it didn't work, I decided not to spent more time on it right now and add it later.

To test:

1. Make sure Scan feature flag is enabled
2. Make sure a site with Scan feature is selected
3. Open Scan
4. Click on "History" action in the toolbar
5. Notice a viewpager with 3 tabs (3 ScanHistoryListFragments) is shown.
6. Scroll down and notice the toolbar is lifted as you start scrolling (z-axis)

PR submission checklist:

• I have considered adding unit tests where possible.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
