feat: Sort/Import Tokens in Mobile (#11618)

## **Description**

Implements Token Sorting on mobile. This is the mobile implementation of
the same feature on extension:
MetaMask/metamask-extension#27184

Note that this currently includes a patch of the
`PreferencesController`. There is a corresponding PR in core to add this
to a formal controller release:
MetaMask/core#4747

## **Related issues**

Fixes: https://consensyssoftware.atlassian.net/browse/MMASSETS-357

## **Manual testing steps**

Go to Portfolio Screen
Sort should allow sorting by declining fiat balance by default. Users
can then toggle and sort alphabetically or by declining fiat balance.

Import button should function the same as the import token link in
footer
