fix(werc20): WERC20 refactors and handling of fallback and receive functions

[Vvaradinov]

Description

This PR refactors some functionality on the WERC20 precompile as discovered through integration tests. In particular:

• the deposit function is payable and thus would trigger the minting/burning mechanism because it's a change of account balance. We manually override it by using the stateDB directly
• handling the receive and fallback functions which will not have a methodID, done in the common precompile setup
