1793: Fix outer doc-comments of `macro_rules` r=matklad a=uHOOCCOOHu Document comments of `macro_rules!` is currently parsed outside the `MACRO_CALL` node, which makes `DocCommentsOwner::doc_comments()` always empty. For the input: ```rust /// Some docs macro_rules! foo { () => {}; } ``` Current parsing tree is: ``` SOURCE_FILE COMMENT // <- This should be children of MACRO_CALL WHITESPACE MACRO_CALL PATH <...omitted...> ``` It should be: ``` SOURCE_FILE MACRO_CALL COMMENT WHITESPACE PATH <...omitted...> ``` Co-authored-by: uHOOCCOOHu <hooccooh1896@gmail.com>
