Hide Wallet Balances

Add a button to hide balances on MetaMask mobile and secondarily, on the desktop extension.

To protect user privacy and security. On mobile, there is a higher chance that people may view the user’s screen with the wallet balance, which could open that user to an attack, theft, or scam. This would also be applicable on desktop in public places.

Mobile first but would also be useful on desktop extension.

Here is a screenshot example of how SafePal hides balances with asterisks.
