Merge #19779: Remove gArgs global from init

fa9d5902f7 scripted-diff: gArgs -> args (MarcoFalke)
fa33bc2dab init: Capture copy of blocknotify setting for BlockNotifyCallback (MarcoFalke)
fa40017706 init: Pass reference to ArgsManager around instead of relying on global (MarcoFalke)

Pull request description:

  The gArgs global has several issues:

  * gArgs is used by each process (bitcoind, bitcoin-qt, bitcoin-wallet, bitcoin-cli, bitcoin-tx, ...), but it is hard to determine which arguments are actually used by each process. For example arguments that have never been registered, but are still used, will always return the fallback value.
  * Tests may run several sub-tests, which need different settings. So globals will have to be overwritten, but that is fragile on its own: e.g. https://github.com/bitcoin/bitcoin/pull/19704#issuecomment-678259092 or #19511

  The goal is to remove gArgs, but as a first step in that direction this pull will change gArgs in init to use a passed-in reference instead.

  ryanofsky:
    Code review ACK fa9d5902f7. Looks good. Nice day to remove some globals, and add some lambdas 👍
  fanquake:
    ACK fa9d5902f7 - I'm not as familiar with the settings & argument handling code, but this make sense, and is a step in the right direction towards a reduction in the usage of globals. Not a huge fan of the clang-formatting in the scripted diff.
