PR Checks: disable tests for Swift on Linux until CLI 2.17.4

[angelapwen]

With the new Linux runner image rollout and CLI versions <= 2.17.3, all PR checks with Swift are failing. This PR disables those tests to unblock CI for now. When CLI version 2.17.4 makes it to nightly-latest and latest, we will re-enable these tests.

The failing PR checks that were previously running on both ubuntu and macos have been updated to only run on macos for now. The failing PR checks that were previously running on only ubuntu have also been updated to only run on macos for now, so that we are at least covering these checks on one operating system.

Now that the debug artifacts check runs on macos instead of ubuntu, old versions of the CLI <2.15.1 are experiencing the known build tracer bug on ARM Macs, so those are disabled for now as well. We programmatically disabled those for the generated PR checks in https://github.com/github/codeql-action/pull/2261.
