build(workflows): remove Node.js v12/v14 from macOS test matrix

The macos_test, macos_benchmark, and macos_test_cov workflows use
macOS-latest, which now resolves to macOS 15 on arm64 (Apple
Silicon). Node.js v12 and v14 have no official arm64 macOS binaries;
actions/setup-node@v6.4.0 fails with "Unable to find Node version
'12' for platform darwin and architecture arm64."

Both versions are EOL (v12 since December 2022, v14 since April
2023) and are still covered by linux_test.yml on x64. Remove them
from the macOS matrices, consistent with macos_test_npm_install.yml
which already excludes them.
