Merge bitcoin/bitcoin#19499: p2p: Make timeout mockable and type safe, speed up test

fadc0c80ae p2p: Make timeout mockable and type safe, speed up test (MarcoFalke)
fa6d5a238d scripted-diff: Rename m_last_send and m_last_recv (MarcoFalke)

Pull request description:

  Use type-safe time for better code readability/maintainability and mockable time for better testability. This speeds up the p2p_timeout test.

  This is also a bugfix for intermittent test issues like: https://cirrus-ci.com/task/4769904156999680?command=ci#L2836

  Fixes #20654
