[CIVIS-9813] Fix for test sdk integration

[ncreated]

What and why?

📦 Re-attempt on #1833 after fixing linter and bumping swiftlint in #1850

From original PR:

Swift testing library is using MachPorts to communicate with this library. They are unique for OS kernel, so each process should have a unique name for them. Right now we are using hardcoded names, so two running test processes will fail.

How?

Testing library sets CI_VISIBILITY_MESSAGE_CHANNEL_UUID variable which is used for name generation for MachPorts.

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)
• Make sure each commit and the PR mention the Issue number or JIRA reference
• Add CHANGELOG entry for user facing changes

Custom CI job configuration (optional)

• Run unit tests for Core, RUM, Trace, Logs, CR and WVT
• Run unit tests for Session Replay
• Run integration tests
• Run smoke tests
• Run tests for tools/
