This is the first step to tease off Osd compute controller/contexts from Far API. Currently FarStencilTable only creates a kernelbatch for the entire range, so we can use [0, numStencils) for all cases instead of KernelBatch. This might not be true if we apply non-factorized level-wise stencils, then we'll add another modular utility to serve those cases.
