Make @import prelude parsed using the streaming parser.

There is one exception still: If there's a media query in there,
it is still parsed using the non-streaming parser. However, the
supports part and the prelude in general are parsed streaming.

Note that this fixes a bug (also in the tests) where empty supports(),
or supports() with an invalid declaration inside, would be allowed;
there doesn't seem to be any allowance for this in the grammar
(\<general-enclosed> is not included in the @import grammar, only in
@supports).
