Subject: Add OpenCL 1.2 and 2.0 headers and CLImpl classes

Added stub includes for OpenCL 1.2 and 2.0. Added new CLImpl versions for
1.2 and 2.0 to the build, but left them unused for now. The CL bindings
used by JOCL are still generated from OpenCL 1.1, so the existing Java
code will be able to stay mostly unchanged in the future.
