Warn on inert attributes used on bang macro invocation These attributes are currently discarded. This may change in the future (see #63221), but for now, placing inert attributes on a macro invocation does nothing, so we should warn users about it. Technically, it's possible for there to be attribute macro on the same macro invocation (or at a higher scope), which inspects the inert attribute. For example: ```rust #[look_for_inline_attr] #[inline] my_macro!() #[look_for_nested_inline] mod foo { #[inline] my_macro!() } ``` However, this would be a very strange thing to do. Anyone running into this can manually suppress the warning.
