Update curl to 8.15.0

This updates curl to 8.15.0.

Changelog: https://curl.se/ch/8.15.0.html
Blog: https://daniel.haxx.se/blog/2025/07/16/curl-8-15-0/

A fairly major change here is that support for SecureTransport on macOS
has been dropped. I decided to switch it over to OpenSSL. I don't know
how well this is going to work. Apple's version of curl uses LibreSSL,
with some minor changes. The main concern is how well it will find
certificate stores, since IIRC those can be stored in the Keychain. The
basic tests of accessing regular websites seem to pass for me.
