GH-140052: Add PyTuple_Make[Single,Pair,Triplet] + steal version

[sergey-miryanov]

My WIP version.

• Issue: [C API] Replace PyTuple_Pack(1,2) with PyTuple_Make[Single,Pair] to optimize creation of tuples #140052

[vstinner]

Please create a separated PR just adding the function without modifying code to use them. As I wrote previously, I would prefer to only add 2 functions: MakeSingle() and MakePair(). You should write doc (Doc/c-api/tuple.rst) and tests (Modules/_testcapi/tuple.c and Lib/test/test_capi/test_tuple.py) for new functions.
