build: Port the a11y test suite to Meson

Copy the location of the test data and binaries from the autotools
build, even though it's not really correct; currently we install the
test data under libexecdir, but it should live under datadir, and we
should use `G_TEST_DIST` to figure it out.

The `state` subdirectory is missing.
