This adds an overlay port for curl that adds the features required for HTTP/3. This is not quite compatible with the upstream vcpkg.json, because enabling HTTP/2 makes it use the default SSL backend, which is sectransp for macOS and schannel on Windows. These backends are not compatible with ngtcp2. Additionally, we can not build curl with multiple SSL backends when using ngtcp2. I couldn't find a way to selectively disable/enable dependencies based on what features are enabled, so I made HTTP/2 pick OpenSSL in our overlay port. Upstream vcpkg will likely want to support wolfSSL and GnuTLS backends for ngtcp2, so they'll be additional work to get this into upstream.
