Merge #21209: build: use newer source for libnatpmp

7af2502 build: compile libnatpmp with -DNATPMP_STATICLIB on Windows (fanquake)
ee35745 build: use newer source for libnatpmp (fanquake)

Pull request description:

  The source we are currently using is from 2015. The upstream repo has
  received a small number of bug fixes and improvements since then.
  Including one that fixes an issue for Windows users:  miniupnp/libnatpmp#13.

  The source we are currently using is the most recent "official" release,
  however I don't think it's worth waiting for a new one. The maintainer
  was prompted to do so in Oct 2020, then again in Jan of this year, and
  no release has eventuated. Given libnatpmp is a new inclusion into our
  repository, I think we should be using this newer source.

  This also cleans up a few warnings we currently see in Windows depends builds:
