Tier Two Optimizer Eliminate Function Version Guards

Feature or enhancement

Proposal:

Suggested by @brandtbucher at the PyCon sprints

The tier two interpreter currently adds additional function function guards when it doesn't need to. We can use the function watcher to track when the function version changes and only add the first one.

Similar to the issue for type version guards https://github.com/python/cpython/issues/119258 and the implemented solution https://github.com/python/cpython/pull/119365

Has this already been discussed elsewhere?

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

首先查看相关的 type-version-guard issue 119258、其已实现的 PR 119365，以及链接的 PR 119491 和 119510。预期结果是让 tier two interpreter 使用 function watcher，从而只添加第一个 function version guard，而不是添加冗余的 guard。
