* initial commit with CPU implementation of upscale to shape and test, cuda implementation next * experimental commit to see if dst shape is correct * test version * test * removed unnecessary params * refactor * fixed tests * ggml : metal impl + cleanup + sycl dev warnings * patched ggml_upscale cuda op to handle non-contiguous tensors, added test for non-contiguous behavior * metal : fix upsacle op to support nb00 + style --------- Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>
