common: delete StringToAddress, StringToHash (#16436)

* common: delete StringToAddress, StringToHash

These functions are confusing because they don't parse hex, but use the
bytes of the string. This change removes them, replacing all uses of
StringToAddress(s) by BytesToAddress([]byte(s)).

* eth/filters: remove incorrect use of common.BytesToAddress
