[rustdoc] Include attribute and derive macros when filtering on "macros"

As discussed [here](rust-lang#147909), some filters should have been "grouped". This PR allows attribute and derive macros to match the `macro` filter.

I'll wait for rust-lang#148005 to add more tests as it would require a proc-macro library for now.
