Subject: [PATCH 1/2] [CI] Remove mac14.

- Remove mac14 because there's no more CI runners for this platform.
- The two intel runners are now running mac15.
- Move the selection of C++23 into the build config instead of a CI
  override.

(cherry picked from commit 7b6dc3902aad337d354c73ab4a65b81cb5fe8abd)
