Many functions in dictobject.c take a `PyInterpreterState *interp` parameter, but none of them use it.

[markshannon]

The parameter was introduced when the global dictionary version number was moved to the interpreter state.
#102338

We no longer have a global dictionary version number so this parameter can be removed.

• gh-142890: remove unnecessary interp parameter from dict functions and _PyDict_NotifyEvent #142923

[kumaraditya303]

I had removed the redundant ones in #136673, the rest of functions need to it to call _PyDict_NotifyEvent. In which functions is it unused?

[colesbury]

It looks like _PyDict_NotifyEvent doesn't use the interp argument, so we can probably remove it there too.

#142923 removes it from rest of dict functions and _PyDict_NotifyEvent.
