Add resize function for aten.upsample_nearest2d.vec operator (#4069)

Summary:
Pull Request resolved: https://github.com/pytorch/executorch/pull/4069

aten.upsample_nearest2d.vec is an operator in OCR model (Neck module). We added support to not decompose this op when lowering to Vulkan delegation. Add resize function so that we only need to build the graph once to test input with different sizes.
