Python 3.13 moved the private _PyUnicode_EQ() function to internal C API.mypy andPyodide are using it.

I propose to add a public PyUnicode_Equal(a, b) function to the limited C API 3.14 to replace the private _PyUnicode_EQ() function:

• Return1 ifa is equal tob.
• Return0 ifa is not equal tob.
• Set aTypeError exception and return-1 ifa orb is not a Pythonstr object.
• The function always succeed ifa andb are strings.
