301bd41a2e6765b185bd55f4c541f9e27aeea29d scripted-diff: Rename InitInterfaces to NodeContext (Russell Yanofsky)

Pull request description:

  This change is mainly a naming / organization change intended to simplify #10102. It:

  - Renames struct InitInterfaces to struct NodeContext and moves it from
    src/init.h to src/node/context.h. This is a cosmetic change intended to make
    the point of the struct more obvious.

  - Gets rid of BanMan and ConnMan globals making them NodeContext members
    instead. Getting rid of these globals has been talked about in past as a way
    to implement testing and simulations. Making them NodeContext members is a
    way of keeping them accessible without the globals.

  - Splits g_rpc_interfaces global into g_rpc_node and g_rpc_chain globals. This
    better separates node and wallet rpc methods. Node RPC methods should have
    access NodeContext, while wallet RPC methods should only have indirect access
    to node functionality via interfaces::Chain.

  - Adds NodeContext& references to interfaces::Chain class and the
    interfaces::MakeChain() function. This is needed to access ConnMan and BanMan
    instances without the globals.

  - Gets rid of redundant Node and Chain instances in Qt tests. This is
    needed due to the previous MakeChain change, and also makes test setup a
    little more straightforward. More cleanup could be done in the future, but it
    will require deduplication of bitcoind, bitcoin-qt, and TestingSetup init
    code.
