[glib/wip/ebassi/test-report] ci: Generate a cover report for the test suite

    ci: Generate a cover report for the test suite
    
    GitLab can show the results of a CI pipeline if the pipeline generates a
    report using the JUnit XML format.
    
    Since Meson provides a machine parseable output for `meson test`, we can
    take that and turn it into XML soup.
