Cover all the Mapping Protocol, almost all the Sequence Protocol
(except PySequence_Fast) and a part of the Object Protocol.
Move existing tests to Lib/test/test_capi/test_abstract.py and
Modules/_testcapi/abstract.c.
Add also tests for PyDict C API..

* Strings with length from 2**31-1 to 2**32-2 always caused MemoryError,
it doesn't matter how much memory is available.
* Strings with length exactly 2**32-1 caused OSError.
* Strings longer than 2**32-1 characters were truncated due to integer overflow bug.
* Strings containing the null character were truncated at the first null character.
Now strings longer than 2**31-1 characters caused OverflowError and the null character is allowed..

The _xxsubinterpreters module was meant to only use public API. Some internal C-API usage snuck in over the last few years (e.g. gh-28969). This fixes that.

[3.12] gh-106033: Get rid of new occurrences of PyDict_GetItem and PyObject_HasAttr (GH-106034)
These functions are broken by design because they discard any exceptions raised
inside, including MemoryError and KeyboardInterrupt. They should not be
used in new code.
(cherry picked from commit 1d33d53780)
