Misc dependency improvements (#4545)

Browse Source 
A couple more uncontroversial changes extracted from #3886.

* Enable full feature of syn
  
   It is necessary for the ItemFn and ItemTrait type. Currently it is indirectly
   enabled through the tracing dependency of bevy_utils, but this may no
   longer be the case in the future.
* Remove unused function from bevy_macro_utils
