lavfi/opencl: Derive global work size from plane image sizes
Add a new function to find the global work size given the output image and
the required block alignment, then use it in the overlay, program and unsharp
filters. Fixes the overlay and unsharp filters applying the kernel to
locations outside the frame when subsampled planes are present.
