WCIP-11: Update Session Params

[pedrouid]

Right now the current interface for Session Params includes the following parameters (L129)

interface ISessionParams {
    approved: boolean
    chainId: number | null
    accounts: string[] | null
    peerId?: string | null
    peerMeta?: IClientMeta | null
  }

However it would be beneficial to add some extra parameters like networkId (required) and rpcUrl (optional). These would be analogous to the proposed changes on EIP-2015. Therefore the new Session Params interface would look as follows:

interface ISessionParams {
    approved: boolean
    chainId: number | null
    networkId: number | null
    accounts: string[] | null
    rpcUrl?: string | null
    peerId?: string | null
    peerMeta?: IClientMeta | null
  }

can we specify for the case that networkId is null a default is used that is based on the chainId

[pedrouid]

Technically that would be incorrect but it would also work for ~73% of the known EVM chains (according to ethereum-lists/chains data)

However if we weigh the network usage of those 73%, we can also make a case that it over 95% of the usage will use the same networkId and chainId
