This commit bundles the personal sign and the signTypedData_V4 sign request in the same command.
The only difference between these two requests is the order of address and challenge in the params array.
What has changed:
1. PersonalSign.. has been renamed to Sign
2. `getPersonalSignParams` renamed to `getSignParams` and implements the parsing for both personal sign and signTypedData_V4
