Summary: X-link: facebookresearch/FBGEMM#796 This diff implements `generate_vbe_metadata` for cpu, such that the function returns the same output for CPU, CUDA and MTIA. To support VBE on CPU with existing fixed-batch-size CPU kernel, we need to recompute offsets, which is previously done in python. This diff implements offsets recomputation in C++ such that all manipulations are done in C++. Note that reshaping offsets and grad_input to work with existing fixed-batch-size CPU kernels are done in Autograd instead of wrapper to avoid multiple computations. VBE CPU tests are in the next diff. Differential Revision: D69162870
