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

首先檢視相關的 type-version-guard issue 119258、其已實作的 PR 119365，以及連結的 PR 119491 和 119510。預期結果是讓 tier two interpreter 使用 function watcher，因此只新增第一個 function version guard，而不是新增多餘的 guard。
