[code-reflection] RFR: [hat][API] ComputeRange moved to NDRange

[Juan Fumero]

This PR refactors the `NDRange` and the `ComputeRange`.

NDRange removes the need for the accelerator object, and the internal kernelContext. 

Instead the `ComputeRange` has been moved to an `NDRange`. Thus, from this change, this is how we will dispatch kernels:


NDRange ndRange = NDRange.of(new Global2D(globalSize, globalSize), new Local2D(BLOCK_SIZE, BLOCK_SIZE));
        cc.dispatchKernel(ndRange,
                kc -> matrixMultiplyKernel2DLI(kc, matrixA, matrixB, matrixC, globalSize)
        );


We add also a set of factory methods to facilitate composing NDRanges when 1D is required :

For instance:


cc.dispatchKernel( NDRange.of(call.length()), 
   kc -> blackScholesKernel(kc, call, put, S, X, T, r, v)
 );
