refactor: Move GetDifficulty out of `rpc/server.h`
It has no business in `rpcserver.h`. Define it in the interface header
of the implementation unit `rpcblockchain` where it is defined.
Also modernize the signature to:
double GetDifficulty(const CBlockIndex* blockindex = nullptr);
(remove `extern`, replace `NULL` with `nullptr`)
