Fix JOGL GLContextImpl ProcAddressTable and Extension Caching

Bug caused using wrong extension cache and probably the wrong procAddress table.

- do not reuse local field value if not cached
- issue resetState() after each createContextARBMapVersionsAvailable(..) query
- remove cache entry for extension (copy/paste bug)
- resetState() shall clean platform extProcAddressTable in specializations
