mesa/tests: Add tests for the generated shared-glapi dispatch table

These are largely based on the src/mapi/glapi/tests.  However,
shared-glapi provides less external visibility into the dispatch table,
so there is less to test.  Also, shared-glapi does not implement
_glapi_get_proc_name, so that test was removed.
