  [docs] Rewrite libc docs from reST to markdown (#208374)

Tracking issue: https://github.com/llvm/llvm-project/issues/201242
Migration guide docs:
https://llvm.org/docs/SphinxQuickstartTemplate.html#markdown-migration-guidelines
RFC:
https://discourse.llvm.org/t/rfc-make-myst-markdown-the-llvm-docs-format-rip-rest/90840

This was prepared with rst2myst plus LLM-assisted cleanup. I paged
through all the generated HTML looking for migration artifacts, and all
of the differences I could find appear to be formatting error
corrections. Please spot check my work and approve if it looks good. You
can use the HTML links below to confirm it renders properly.
