RFR: 8348895: [testbug] Skip failing 3D lighting tests on macOS 14 or later on aarch64

[Kevin Rushforth]

We currently skip 4 failing lighting tests on macOS 14 / aarch64. Those same tests fail on macOS 15 now, so this modifies the check used to skip those tests to macOS 14 _or later_ / aarch64.

I'll run a CI test build on macOS 15 with this fix and the fix in PR #1685.
