removed CLContext factory methods with CLPlatform + CLDevice list combinations.

justification:
 - information is now no longer needed since every CLDevice knows its CLPlatform
 - OpenCL device IDs are not portable between CLPlatforms

changes:
 - Context factories will throw CLInvalidPlatformException if the platform of all CLDevices does not match

related changes:
 - [persistance] CLProgramBuilder stores now the ICD suffix to be later able to map binaries back to the platform + device
