Add PyFrame_SetLineNumber() for Cython

Feature or enhancement

Proposal:

CPython hides PyFrameObject internals so Cython include pycore_frame.h to set f_lineno.
Let's provide PyFrame_SetLineNumber() for Cython.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

该提案没有指定源文件或测试。首先查看 PR 117551 中之前的讨论以及链接的 PR gh-131246；所要求的结果是提供一个公开的 PyFrame_SetLineNumber() API，使 Cython 无需包含 pycore_frame.h。通过检查该 API 已公开并可用于所述的 Cython 使用场景，确认工作已完成。
