dev-python/cython: rework tests

* Make numpy conditional on USE=test-full

  numpy doesn't pass tests on some niche arches and maybe we'll even
  be able to destable it on the really niche arches at some point thanks
  to this.

* Make numpy conditional on PYTHON_FULLY_TESTED

  numpy depends on cython and porting numpy to a new Python impl often
  takes a while, so let's make it easy to get partial coverage.

* Fix numpy test dep (doesn't need to be <2 for a while now).

  Sent https://github.com/cython/cython/pull/6895 upstream as well.

* Enable tests for py3.13, py3.14, and pypy3_11

* More robust skips for coverage tests which have had problems before

  They're not interesting for us in packaging.

* Add some notes about other possible test deps we could add in future.
