f0e22be69a build: no-longer disable WARN_CXXFLAGS when CXXFLAGS is set (fanquake)
b088062e68 ci: remove -Wdocumentation from -Werror in multiprocess CI (fanquake)

Pull request description:

  Now that `CXXFLAGS` are [back in user control](https://github.com/bitcoin/bitcoin/pull/24391), I don't think there's a
  reason to no-longer use our warning flags when `CXXFLAGS` has been
  overriden (this includes, by default, when building from depends).

  Anyone can suppress warnings from third-party code by
  passing the relevant `-Wno-` options in `CXXFLAGS`.

  Closes: #18092.
