coin: Bump macOS host templates to 13

We support Xcode 14 (SDK 13) as the minimum, documented on
https://doc-snapshots.qt.io/qt6-dev/macos.html

Bump our macos static tests and ios tests platforms to build on macOS
13, just like all other macos configs, and to also follow what we
document.

We can then enforce the minimum SDK version as a build time error
when building qtbase.
