Add a QT_REQUIRE_CONFIG(feature) macro

This macro expands into a static_assert and can be used to
trigger a compile error if a certain feature is not available
when trying to compile some code.

This is especially useful to protect against accidental inclusion
of headers that implement functionality related to a feature.
