[libc++] Add CI without experimental features and don't exclude span from the tests

[ldionne]

Summary

There is no reason for the parts of std::span that don't depend on ranges
to be disabled when ranges aren't provided. Also, to make sure the
"no-experimental-stuff" configuration is tested, add a CI job for it.

[jloser]

Looks reasonable to me modulo my comment about missing the XFAIL: apple-clang-12.0.0 on libcxx/test/std/containers/views/span.cons/deduct.pass.cpp

If we remove this, do we need to replace it with XFAIL: apple-clang-12.0.0? This goes for other span tests too, but most (all but this one?) have the XFAIL already.

I don't think we need the XFAIL here because we are not using concepts in this test AFAICS. CI will let us know if we need to add it.

Looks like you're right according to CI. :)
