* Allow per-interpreter internals/local_internals
* Significant rewrite to avoid using thread_locals as much as possible.
Since we can avoid them by checking this atomic, the cmake config conditional shouldn't be necessary.
The slower path (with thread_locals and extra checks) only comes in when a second interpreter is actually instanciated.
* Add a test for per-interpreter GIL
Uses two extra threads to demonstrate that neither shares a GIL.
* Fix for nonconforming std::atomic constructors on some compilers
* style: pre-commit fixes
* Fix initializer to make MSVC happy.
* Switch to gil_scoped_acquire_simple, get rid of old copy of it from internals.h
* Use the PyThreadState's interp member rather than the thread state itself.
* Be more explicit about the type of the internalspp
* Suggested renamings and rewordings
* Rename find_internals_pp and change it to take in the state dict reference
* Use the old raise_from instead of pybind11_fail
* Move most of the internals initialization into its constructor.
* Move round_up_to_next_pow2 function upwards
* Remove redundant forward decl
* Add a python-driven subinterpreter test
* Disable the python subinterpreter test on emscripten
Can't load the native-built cpp modules.
* Switch the internals pointer pointer to a unique_ptr pointer
* Spelling
* Fix clang-tidy warning, compare pointer to nullptr
* Rename get_interpreter_counter to get_num_interpreters_seen
* Try simplifying the test's cmake set_target_properties
* Replace mod_* tags with a single tag w/enum
Update tests accordingly
* Add a test for shared-GIL (legacy) subinterpreters
* Update test to work around differences in the various versions of interpreters modules
* Fix unused parameter
* Rename tests and associated test modules.
* Switch get_internals_pp to a template function
* Rename curtstate to cur_tstate
* refactor: use simpler names

* Have to join these threads to make sure they are totally done before the test returns.
* Wrap module_def initialization in a static so it only happens once.
If it happens concurrently in multiple threads, badness ensues....
* style: pre-commit fixes
