Previously when I wrote this document, I felt the completed scripts was
lengthy, redundant and not easy to read. So I didn't add complete
examples in the previous commit.
However, in the recent discussion with @avogelsgesang, I found people
may not know how to use debugging scripts to improve their debugging
efficiency. So now, I feel like it is helpful to put the examples even
if they are a little bit long.
Test Plan: make docs-clang-html

Previously in D99179, I tried to construct debug information for
coroutine frames in the middle end to enhance the debugability for
coroutines. But I forget to add ReleaseNotes to hint people and
documents to help people to use. My bad. @probinson revealed this in
https://github.com/llvm/llvm-project/issues/55916.
So I try to add the use document now.
