This PR backports the error codes from the spec. This relies on two specs for defining the error codes: - Our rpc-spec-v2 https://github.com/paritytech/json-rpc-interface-spec. - JSON-RPC spec https://www.jsonrpc.org/specification#error_object. To better describe the error codes, they are divided into two separate modules `rpc_spec_v2` and `json_rpc_spec` respectively. The `InvalidSubscriptionID` and `FetchBlockHeader` are merged into the JSON-RPC spec `INTERNAL_ERROR`. While the other error codes are adjusted from spec. Errors that are currently in use: - -32801 block hash not reported by chainHead_follow or block hash has been unpinned - -32802 chainHead_follow started with withRuntime == false - -32803 chainHead_follow did not generate an operationWaitingForContinue event The following are errors defined in the [JSON-RPC spec](https://www.jsonrpc.org/specification#error_object): - -32602 The provided parameter isn't one of the expected values, has different format or is missing - -32603 Internal server error Note: Error `-32801` must be introduced and generated by the outstanding https://github.com/paritytech/polkadot-sdk/issues/1505 Closes: https://github.com/paritytech/polkadot-sdk/issues/2530 --------- Signed-off-by: Alexandru Vasile <alexandru.vasile@parity.io>

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
