[TEMP CHECK] Add stMATIC and wstETH as depositable assets

Adding LST assets will allow users to hold interest bearing tokens inside the privacy rollup. Users gain more privacy when assets are stored long term inside the network, slowly spending them over time.

Adding these assets degrades the current privacy set and users are now split between depositing either MATIC/WETH or stMATIC/wstETH. If the community prefers LSTs, the native versions could be deprecated in a future proposal.
