rzou f8fcc54f70 Add torch.library.impl_abstract (#109912)
Changelog:
- torch.library.impl_abstract optionally accepts a torch.library.Library
  object. If passed in, then the lifetime of the registration is tied to
  the Library object.
- we've also changed torch.library.impl_abstract to work on all
  operators, including overloads.
- we refactored the `torch._custom_ops.*` and `torch._custom_op.*`
  impl_abstract APIs and put them under torch._library. This is the
  final resting place for them. I will follow-up with deleting
  all the `torch._custom_ops.*` stuff later.
- There is a new "SimpleOperatorRegistry" where we actually collect the
  abstract_impl. We will expand this to also hold the other
  torch._custom_ops.* APIs when we move those to torch.library

NB: Previously we had designed
`impl_abstract` assuming a very high-level Python-only custom op API.
We've revisited that since; now, impl_abstract works for all custom ops,
no matter python or C++, no matter the schema. The new refactored design
reflects this better.

Test Plan:
- existing and new tests
