Changes

Add new kernel workgroup info functions to CLKernel

Added workgroup info functions for OpenCL 1.1, since that's the version
the CL Java objects currently wraps. Also added a test that shows how to
query values from version 1.2 and later.

Remove non-functional CL_KERNEL_GLOBAL_WORK_SIZE test

This test didn't work properly, since that property only applies to
custom devices and built-in kernels.

Changes CLMemory's getNIOSize() and getNIOCapacity() to use buffer.limit() instead of capacity() in order to respect the user's desired buffer size in memory operations.

Changing CLBuffer#create to respect the limit instead of capacity on the direct buffer that the CLBuffer is being created for as this more closely represents the users intention about the buffer size.

Adopt to GlueGen change: Drop ManualStaticInitCall, PointerBuffer.ELEMENT_SIZE -> AbstractBuffer.POINTER_SIZE
