This is a companion to #118583, although it can be landed independently because since #117922 dialects do not have to use the same Python binding framework as the Python core code. This PR ports all of the in-tree dialect and pass extensions to nanobind, with the exception of those that remain for testing pybind11 support. This PR also: * removes CollectDiagnosticsToStringScope from NanobindAdaptors.h. This was overlooked in a previous PR and it is duplicated in Diagnostics.h. --------- Co-authored-by: Jacques Pienaar <jpienaar@google.com>
