[llvm-branch-commits] [clang] [docs] Rewrite selected Clang docs to Markdown (PR #209283)

I spot-checked the files and don't have any concerns. There are definitely some formatting fixes that happened (I see some stuff going from italics to code font, which is great). I spotted some visual differences with spacing between words, but nothing seems harder to read for my eye and so I think it's fine.

LGTM, thank you!
