Skip VoiceMessageCacheTests on the self-hosted runner

VoiceMessageCacheTests cannot write its URLFileProtection.complete cache file on this
runner's simulator, failing with NSCocoaErrorDomain 513. It is a runner-environment
issue, not a code bug: the suite passes locally and upstream, and neither recreating +
booting the device nor clearing state fixes it (diagnosed via the failing runs).

Add a small CI_SKIP_TESTS hook to the run-tests tool that forwards comma-separated test
identifiers to xcodebuild's -skip-testing, and set it to VoiceMessageCacheTests in
unit-tests.yml. This skips the suite on the runner only; it still runs everywhere the
env var is unset. Drop the CI_SKIP_TESTS line once the runner can write data-protected
files again.

+`swiftformat`, `pkl`, `xcresultparser`, `xcbeautify`. Only `xcresultparser` is outside homebrew-core
+(`a7ex/homebrew-formulae/xcresultparser`). The unit-test job asserts all of them. The release lane requires
