signer, clef: implement EIP191/712 (#17789)

* Named functions and defined a basic EIP191 content type list

* Written basic content type functions

* Added ecRecover method in the clef api

* Updated the extapi changelog and addded indications in the README

* Changed the version of the external API

* Added tests for 0x45

* Implementing UnmarshalJSON() for TypedData

* Working on TypedData

* Solved the auditlog issue

* Changed method to signTypedData

* Changed mimes and implemented the 'encodeType' function for EIP-712

* Polished docstrings, ran goimports and swapped fmt.Errorf with errors.New where possible

* Drafted recursive encodeData

* Ran goimports and gofmt

* Drafted first version of EIP-712, including tests

* Temporarily switched to using common.Address in tests

* Drafted text/validator and and rewritten []byte as hexutil.Bytes

* Solved stringified address encoding issue

* Changed the property type required by signData from bytes to interface{}

* Fixed bugs in 'data/typed' signs

* Brought legal warning back after temporarily disabling it for development

* Added example RPC calls for account_signData and account_signTypedData
