neorpc: add deprecated error codes for C#-compatibility

Browse source 
While our server no longer uses these codes (-100, -400) they still can come
from C# servers and while we consider them deprecated we better at least have
some definition of them until C# implements our proposal:
https://github.com/neo-project/proposals/pull/156
Also adding description of deprecated RPC error codes in ROADMAP.md.

Removal of `serv_node_version` is scheduled for Sep-Oct 2023 (~0.105.0 release).
## RPC error codes returned by old versions and C#-nodes
NeoGo retains certain deprecated error codes: `neorpc.ErrCompatGeneric`,
`neorpc.ErrCompatNoOpenedWallet`. They returned by nodes not compliant with the
neo-project/proposals#156 (NeoGo pre-0.102.0 and all known C# versions).
Removal of the deprecated RPC error codes is planned once all nodes adopt the new error standard.
