Erc20::approve for DestinationType::Contract

Browse Source 
This allows the CREATE code to bork without the Serai router losing access to
the coins in question. It does incur overhead on the deployed contract, which
now no longer just has to query its balance but also has to call the
transferFrom, but its a safer pattern and not a UX detriment.

This also improves documentation.
