interpreter, mtest: introduce add_test_setup(exclude_suites: ...)

This new keyword argument makes it possible to run specific
test setups only on a subset of the tests.  For example, to
mark some tests as slow and avoid running them by default:

    add_test_setup('quick', exclude_suites: ['slow'], is_default: true)
    add_test_setup('slow')

It will then be possible to run the slow tests with either
`meson test --setup slow` or `meson test --suite slow`.
