Subject: [PATCH] webdriver chore: check browsing context existence before
 handling user prompt when required (#38142)

Thanks to Trong with #38035, we can finally handle user prompt. This PR
is mainly dirty work:
1. Add browsing context check before handling user prompt when required,
according to spec.
2. Reduce IPC by removing redundant context existence check.
3. Add many missing docs.

Testing: New passing cases and turn some ERROR into FAIL.
