Subject: EIP-1186 eth_getProof (#17737)

* first impl of eth_getProof

* fixed docu

* added comments and refactored based on comments from holiman

* created structs

* handle errors correctly

* change Value to *hexutil.Big in order to have the same output as parity

* use ProofList as return type
