convert Interop to Truffle Libraries

[lukasstadler]

These changes mainly update the interop code in grCUDA (in DeviceArray, etc.) to the new interop API in Truffle.
Additionally, there's some other minor updates:

• Modify the makefile that runs the parser generator to generate only the necessary files (no listeners, etc.) and to pre-process all files at once (fixes build problems).
• Don't store the context in the language, and use @CachedContext(GrCUDALanguage.class) in the right places.

There is one bug in DeviceArrayFunction. There is a new DeviceArrayTest Unit test I plan to merge soon.

Thanks, these changes look good to me. The polyglot language tests are passing as well.
Go ahead, you should be able to merge the PR if this is setup correctly.
