GHA: drop quictls 3.3.0 builds in favor of openssl 3.5+
- http3-linux: move local nghttpx (nghttp2) build to openssl (from
quictls). Also tried LibreSSL, but it made some HTTP/2 tests fails.
- http3-linux: drop quictls ngtcp2 build.
- http3-linux: build local openssl with `no-deprecated`.
(previously tested in the quictls local build.)
- http3-linux: explicitly disable LDAP in cmake openssl jobs.
cmake builds auto-detect OpenLDAP (autotools don't), and when enabled,
linking curl fails because system `libsasl.so` requires MD5 openssl
functions, which are missing from openssl no-deprecated builds.
- macos: move options tested in quictls jobs to other ones.
- linux: drop unused quictls local build. (it was used for msh3.)
