gh-121485: Always use 64-bit integers for integers bits count (GH-121486)

to represent the number of bits in Python integer.

gh-116417: Move limited C API long.c tests to _testlimitedcapi (#117001) 
* Split long.c tests of _testcapi into two parts: limited C API tests
  in _testlimitedcapi and non-limited C API tests in _testcapi.
* Move testcapi_long.h from Modules/_testcapi/ to
  Modules/_testlimitedcapi/.
* Add MODULE__TESTLIMITEDCAPI_DEPS to Makefile.pre.in.

gh-111140: Improve PyLong_AsNativeBytes API doc example & improve the test (#115380) 
This expands the examples to cover both realistic use cases for the API.
    
I noticed thing in the test that could be done better so I added those as well: We need to guarantee that all bytes of the result are overwritten and that too many are not written.  Tests now pre-fills the result with data in order to ensure that.
