Bumps numpy version to 1.22.3, cython version to 0.29.28 and fixes numpy build on macOS

[misl6]

• Recipe: cython 0.29.15 --> 0.29.28 (0.29.15 is not compatible with latest numpy, and 0.29.28 is the max supported verison declared in Kivy.
• Recipe: numpy 1.18.1 --> 1.22.3 (which is now compatible with [WIP] Add support for Python 3.10 and make it the default while building hostpython3 and python3 #2566)
• Fixed build of numpy on macOS (See: Numpy on MacOsX fails in our CI tests #2087 and error building numpy with bulldozer buildozer#1426)
• compiler_cxx_fix.patch now looks un-neeeded.
• hostnumpy-xlocale.patch breaks build for the macOS host, and should be handled via https://github.com/numpy/numpy/blob/3544fae2859d8ecac378b9ddc8f909c69455a831/numpy/core/src/common/numpyos.c#L19

✅ The produced bdist_unit_tests_app-debug-1.1-.apk passes the numpy tests.
⚠️ macOS checks looks good on my local machine, but tests introduced via #2574 are still failing due to an unrelated issue.

@nkehoe you may be interested in testing this one.

Please consider that this is expected to run on top of latest develop branch of python-for-android, which now requires Android NDK 23b.

buildozer still doesn't supports the download of ndk23b, so you'll need to manually download it, and to change your buildozer.spec accordingly.

Feel free to ping me on Discord if you need some help.
