ci(windows-meson-test): handle options and output like other test jobs

The GitHub windows-meson-test jobs directly run "meson test" with the
--slice option. This means they skip all of the ci/lib.sh
infrastructure, and in particular:

  1. They do not actually set any GIT_TEST_OPTS like --verbose-log or
     -x.

  2. They do not do the usual handle_failed_tests() magic to print test
     failures or tar up failed directories.

As a result, you get almost no feedback at all when a test fails in this
job, making debugging rather tricky.

Let's try to make this behave more like the other CI jobs. Because we're
on Windows, we can't just use the normal run-build-and-tests.sh script.
Our build runs as a separate job (like the non-meson Windows job), and
then we parallelize the tests across several job slices. So we need
something like the run-test-slice.sh script that the "windows-test" job
uses.

In theory we could just swap out the "make" invocation there for
"meson". But it doesn't quite work, because "make" knows how to pull
GIT_TEST_OPTS out of GIT-BUILD-OPTIONS automatically. But for meson, we
have to extract them into the --test-args option ourselves. I tried
making the logic in run-test-slice.sh conditional, but there ended up
being hardly any common code at all (and there are some tricky ordering
constraints). So I added up with a new meson-specific test-slice runner.
