meson: use a feature option for tests instead of boolean

This allows tests to be autodetected gracefully, which is particularly
convenient for kyua and atf_sh which are fairly painful to build and
install by hand. Those who want to ensure tests are enabled or disabled
may pass `-Dtests=enabled` or `-Dtests=disabled` respectively.
