util: Remove unused USED macro

Browse source 
The glapi assembly code used to use this to force some symbols to stay
in the link even if they would normally get garbage-collected. We're not
doing that anymore. If we ever need it again we can add it back, and not
conflate its definition with the PUBLIC macro state while we're at it.

/**
* PUBLIC/USED macros
*
* If we build the library with gcc's -fvisibility=hidden flag, we'll
* use the PUBLIC macro to mark functions that are to be exported.
*
* We also need to define a USED attribute, so the optimizer doesn't
* inline a static function that we later use in an alias. - ajax
* This marks symbols that should be visible to dynamic library consumers.
