Fix after changes made in #568 torch.compile doesn't like returning input arguments. So, change the return type of pybind fns to `void`, given that it's already an inplace op. PyTorch Library annotation is applied to a wrapper function for each pybind op. Python API doesn't change. Both inplace and non-inplace versions calls the annotated wrapper function.

Hi, now tvm wrapper build failed cause by #568. I noticed that the new `BatchQKApplyRotary` interface removed `__restrict__` modifier from `DType* q, DType* k, DType* q_rope, DType* k_rope`, so it's trivial to just add one adapter function to fix this issue.

Previously our rope apis assume the position indices of each request is contiguous, which is not appropriate for applications such as speculative decoding, this PR fixes the issue by supporting the huggingface transformer-style API which use
pos_idsargument to specify positions.This PR implements parts of the feature of #530 , other requests are coming in later PRs.
