glapi: Remove handling of mesa_name XML attribute.

Previously, we used the mesa_name XML attribute to make the code
generation scripts aware of any instances where the Mesa
implementation of a function had a different function name suffix than
the primary name in the XML.  Now that all of the Mesa implementation
functions have been renamed to match the XML, this attribute is no
longer necessary.
