This PR updated the intrinsic lowering pass to support the new op registry and avoid overloading the global tvm registry. Meanwhile, it kept the fallback mechanism to find the most suitable lower intrinsic function, e.g., llvm.FLowerIntrinsic vs. default.FLowerIntrinsic. All previous op registration are ported to new functions, and some missing ops would be added in separate PR.

Python side op lowering function has been changed from register_func to register_op.

Thanks for the contribution! A few high-level comments:

  1. Do not add any C API - we can use packed func to expose the interface. Op is a compile-time concept so please move the registration logic out of the runtime :-)
  2. Please change register_op to some name like register_intrin_lowering, and consider accepting a target kind like default/llvm/cuda

Thanks for the advice! I have changed the name of function in python-side to register_op_intrin_lowering and removed change to C API. Instead, I utilized the global function registration and packedfunc to register op intrinsic lowering function.

two minor nits mainly on the api and use TypedPackedFunc over PackedFunc. Overall LGTM!
