python3-numpy: fix ptests

Fix the numpy ptests by doing the following:

- Add meson to ptest RDEPENDS in the recipe;
- Add python3-unittest-automake-output as a ptest RDEPENDS;
- Convert run-ptest to a shell script that sets PYTEST_DEBUG_TEMPROOT to
  a directory inside the same path that contains the script, create that
  directory, and then invoke the tests with `pytest --automake` pointed
  at the numpy path in site-packages (copying the tests into the normal
  PTEST_DIRECTORY seems to cause module import breakages in some tests).
  This also includes skipping two problematic tests which require a C
  compiler and use up a lot of space, respectively;
- Set 'IMAGE_ROOTFS_EXTRA_SPACE = "3048576"' for python3-numpy in
  core-image-ptest.bb;
- Also set 'QB_MEM:virtclass-mcextend-python3-numpy = "-m 4096"' in
  core-image-ptest.bb;
- Move python3-numpy from the PTESTS_PROBLEMS list to the PTESTS_SLOW
  one.

Testsuite summary
DURATION: 87
END: /usr/lib/python3-numpy/ptest
2025-04-29T17:35
STOP: ptest-runner
TOTAL: 1 FAIL: 0

Note that many of the skipped tests are due to the absence of
python3-mypy (which is currently in meta-python) and of a Fortran
compiler.
