This pass was supposed to check use of gated features before `#[cfg]`-stripping but this was not the case since it in fact happens after. Checks that are actually important and must be done before macro expansion are now made where the features are actually used. Close #32648. Also ensure that attributes on macro-generated macro invocations are checked as well. Close #32782 and #32655.
