[www] Change URLs to HTTPS.
This changes most URLs in llvm's html files to HTTPS. Most changes were
search-and-replace with manual verification; some changes were manual.
For a few URLs, the websites were performing redirects or had changed
their anchors; I fixed those up manually. This consistently uses the
official https://wg21.link redirector. This also strips trailing
whitespace and fixes a couple of typos.
Fixes D69363.
There are a very small number of dead links for which I don't know any
replacements (they are equally dead as HTTP or HTTPS):
