Add trio.from_thread.check_cancelled api to allow threads to efficiently poll for cancellation

3

This PR reuses the thread local object in `_threads.py` to stash the `raise_cancel` provided to abort, which basically implements a suggestion by @njsmith in https://github.com/python-trio/trio/issues/961#issuecomment-501597755: >Another idea: in `run_sync_in_thread`, start...

Atomic replace (second attempt)
