gh-106320: Remove private float C API functions (#108430) 
106320: Remove private float C API functions

Remove private C API functions:

* _Py_parse_inf_or_nan()
* _Py_string_to_number_with_underscores()

Move these functions to the internal C API and no longer export them.

bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049) 
Add "z" format specifier to coerce negative 0 to zero.

See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion.
This covers `str.format()` and f-strings.  Old-style string interpolation is not supported.

Eric Smith 0923d1d8d7 The other half of Issue #1580: use short float repr where possible. 
Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.

Also addresses these, which are intertwined with the short repr
changes:

- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515: 'n' formatting with commas no longer works poorly
    with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
    for floats.
