Merge #20027: Use mockable time everywhere in net_processing
b6834e312a6a7bb395ec7266bc9469384639df96 Avoid 'timing mishap' warnings when mocking (Pieter Wuille)
ec3916f40a3fc644ecbbaaddef6258937c7fcfbc Use mockable time everywhere in net_processing (Pieter Wuille)

Pull request description:

  The fact that net_processing uses a mix of mockable tand non-mockable time functions made it hard to write functional tests for #19988.

  I'm opening this as a separate PR as I believe it's independently useful. In some ways this doesn't go quite as far as it could, as there are now several data structures that could be converted to `std::chrono` types as well now. I haven't done that here, but I'm happy to reconsider that.
