refactor: map feature toggle

[emilyjablonski]

This PR addresses bloom-housing#4507

• Addresses the issue in full
• Addresses only certain aspects of the issue

Description

Adds back in the old map files, postfixed with Deprecated.
Adds a new dynamic feature toggle to turn the map experience on / off.

On desktop:
Keeps the UI changes from the new map to have a full screen and new search bar, but uses the old map / only fetches 25 listings

On mobile:
Reverts back to the swipe-up experience, but keeps the full screen map and the new search bar.

Additionally, when the toggle is on, fixes a bug where externally fetched listings weren't showing in info modals after clicking on a pin.

How Can This Be Tested/Reviewed?

With SHOW_ALL_MAP_PINS as false, compare the listings map experience to prod. We will have the full screen maps and placement of the search bar, but the rest should be very similar.

There's lots of lines added from copying and pasting the old files. These Deprecated files have no changes to just a line or two to support toggling. The files were already messy, so I wouldn't focus time there since we're moving away from that version.

I'm unsure if I was supposed to be reviewing this or not. But so far haven't found anything!

The recent changes were to fix a bug where the swipeable area on mobile wasn't always sticky to the top
