Refactor RPC matchBuiltInOp to get rid of exception swallowing (#49009)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49009
As per the title, we should generally not have exception swalling and
this commit makes it so that if there is a true error in JIT operator
resolution, it is propagated back to the RPC callee and we don't silently
swallow any other exceptions that may happen. Swallowing the exceptions
previously resulted in hard to debug issues such as unexpected ops showing up
in profiler, and flaky tests which were fixed by
https://github.com/pytorch/pytorch/pull/41287
Added a unittest that validates the error that comes from `jit/pybind_utils.h`.
