build: Add ci profile that uses --release

As we add more rust crates in performance-critical places,
we run into some performance issues with debug builds.
This makes it hard to get a good feel for the performance
of the application, as something may be slow simply because
it's not been optimized by the compiler.

This commit adds a ci profile to our meson options,
and adjusts our CI configuration to use it. Regular
builds should continue to use the development profile.

Also renames `default` to `release`
