ci: run pyxtest under valgrind memcheck on Ubuntu
Add a dedicated xserver-build-ubuntu-valgrind job that builds a debug
Xvfb and runs the pyxtest suite (test/pyxtest/) with --valgrind, so
memory errors (invalid reads/writes, use-after-free, uninitialised
value use) are caught in CI, not just OOB bugs ASAN happens to catch
locally.

The pytest-based harness (test/pyxtest/conftest.py, xserver.py,
valgrind.py) already implements valgrind support; it was simply never
wired into CI. pytest itself was also not installed in the Ubuntu CI
image, so the existing pyxtest suite has been silently skipped (not
built, since meson's find_program('pytest', required: false) found
nothing) on every other Ubuntu lane too. Installing python3-pytest
fixes that as a side effect: the normal xserver-build-ubuntu* jobs now
also actually run pyxtest (without valgrind) as part of "meson test",
exercising the existing protocol-fuzzing regression tests that were
previously dead weight.

Kept as a separate lane rather than adding --valgrind to the existing
run-xserver-build-and-test.sh: valgrind is slow, and pyxtest only
needs Xvfb, not the full Xorg/Xephyr/Xnest/XTS/piglit build the other
lanes carry.

                        X server test suite

This suite contains a set of tests to verify the behaviour of functions used
internally to the server.

= How it works =
Through some automake abuse, we link the test programs with the same static
libraries as the Xorg binary. The test suites can then call various functions
and verify their behaviour - without the need to start the server or connect
clients.

This testing only works for functions that do not rely on a particular state
of the X server. Unless the test suite replicates the expected state, which
may be difficult.

= How to run the tests =
Run "make check" in the test directory. This will compile the tests and execute
them in the order specified in the TESTS variable in test/Makefile.am.

Each set of tests related to a subsystem are available as a binary that can be
executed directly. For example, run "xkb" to perform some xkb-related tests.

== Adding a new test ==
When adding a new test, ensure that you add a short description of what the
test does and what the expected outcome is.
