Running "make clean" in some directories can break "make test" in
others. That notably happens by running clean somewhere in or below
$(TOPDIR)/src/python, which removes __init__.py files potentially needed
by unit and integration tests in $(TOPDIR)/test.
This commit makes the failure easily visible by introducing the notion
of "testabiltity" - if the tree is not testable, "make test" logs
exactly that in a clear error message and gives up.
Makefiles which need to check "testability" can use it as a
prerequisite. This commit does that with py-run.mk and jw-py-test.mk.
Testability is asserted by running "make", "make all" or "make test"
from $(TOPDIR). A successful toplevel build coincides with testability,
and leaves a $(TOPDIR)/dirs-all.done behind, which is why that file is
the perfect testability marker.
It is automatically created by a toplevel build and cleared by using the
"invalidate-testability" prerequisite. This commit makes target "clean"
depend on it in py-mod.mk. To be extended to other use cases / makefile
snippets as needed.

.mypy_cache, .ruff_cache and .pytest_cache are not consistently
cleaned in all subdirectories. Fix that.

Add a dedicated py-test.mk for running tests with pytest instead of
python.
The commit introduces a new variable PYTHON_RUNNER, which is then
used by py-run.mk to do it's usual thing. Running pytest is similar
enough to running Python programs to keep the rest of the machinery
and prevent redundancy from creeping in.

Every directory should have a test target, and the test target should
depend on all so that all files are generated that might be needed
for testing. This commit fixes some missing targets, and adds some
missing dependencies.

This commit removes everything not strictly necessary for running
"make clean all" inside jw-build.
packaging jw-devtest. This cuts the repo down from 24077 to 4725
lines of code.
The idea is to
1) Further remove bloat from the remaining bits
2) Re-add what's necessary to build and package other essential repos.
The decision should be based on whether or not jw-build can also be
useful in a non-janware context.

This commit flips some more switches from Python 2 to Python 3 in makefiles and
Python code. Build runs through, but it's still likely to break things.
