common/types: add Address.Big (#26132)

Browse source 
Many of the other types have a function to convert the type to a big.Int,
but Address was missing this function.

It is useful to be able to turn an Address into a big.Int when doing
EVM-like computations natively in Go. Sometimes a Solidity address
type is casted to a uint256 and having a Big method on the Address
type makes this easy.
