Ports: Add mirror URL support for downloads

Add support for mirror:// sources in Ports downloads. Resolve mirror
types centrally and try their configured URLs in order.

Add a GNU mirror type using ftpmirror.gnu.org and ftp.gnu.org, migrate
existing GNU ftpmirror sources to use mirror://gnu, and verify pro
downloads against the expected SHA256 so failed responses can fall
back to the next mirror. Switched to dynamic variables like in
\#26427 and replaced readarray with a loop that works on macOS.
