[issue42294] [C API] Add new C functions with more regular reference counting like PyTuple_GetItemRef()

[Serhiy Storchaka]

I concur with Mark.

If you want to work only with non-borrowed references, use PySequence_GetItem() and PySequence_SetItem(). It has a cost: it is slower and needs checking errors. If you need more performant solution and binary compatibility across versions, use PyTuple_GetItem() and PyTuple_SetItem() (borrowed references is the part of optimization). If you don't need binary compatibility, but need speed, use macros.

And no need to expand the C API. It is already large enough.
