* Refactor internals to use a holder that manages the PP

* Refactor internals to use a holder that manages the PP

* Fix cleanup/destruction issues.

* Fix one more destruction issue

Should now just be able to delete the internals PP on destruction

* Make clang-tidy happy

* Try to fix exception translators issue on certain platforms

Also fix a couple more pedantic warings

* Fix test, after internals is free'd it can come back at the same address

So instead, just make sure it was zero'd and don't try to compare the addresses.

Also a little code cleanup

* Comment tweak [skip ci]

* Switch to ifdef instead of if

* Re-enable subinterpreters in iOS

* style: pre-commit fixes

* Oops, this snuck in on merge

* fix: bump ABI version to 10
