Question: running debug builds on xplat without logging?

I couldn't find the answer to this in the wiki or docs if it is there I'm sorry for missing it.

If I run a debug build of ChakraCore on macOS it produces a lot of logging that is rarely of use to me, below is a sample but one run of ch from a debug build with any script at all produces about 5 times this amount :
```
] Init /Users/snip/Documents/ChakraCore/pal/src/synchmgr/synchcontrollers.cpp:59Expression: InternalGetCurrentThread() == pthrCurrent
] SetSignalCount /Users/snip/Documents/ChakraCore/pal/src/synchmgr/synchcontrollers.cpp:563Expression: InternalGetCurrentThread() == m_pthrOwner
] ReleaseController /Users/snip/Documents/ChakraCore/pal/src/synchmgr/synchcontrollers.cpp:742Expression: InternalGetCurrentThread() == m_pthrOwner
] Release /Users/snip/Documents/ChakraCore/pal/src/synchmgr/synchcontrollers.cpp:100Expression: InternalGetCurrentThread() == m_pthrOwner
] Init /Users/snip/Documents/ChakraCore/pal/src/synchmgr/synchcontrollers.cpp:59Expression: InternalGetCurrentThread() == pthrCurrent
] Init /Users/snip/Documents/ChakraCore/pal/src/synchmgr/synchcontrollers.cpp:59Expression: InternalGetCurrentThread() == pthrCurrent
] CanThreadWaitWithoutBlocking /Users/snip/Documents/ChakraCore/pal/src/synchmgr/synchcontrollers.cpp:153Expression: InternalGetCurrentThread() == m_pthrOwner
```

Additionally if I run the test suite with a debug build it produces all of this logging - which causes every single test to fail as the logging is not in the baselines.

Please could someone tell me how to disable this so I can:
- ensure any new code I've written doesn't hit asserts whilst passing tests in the test suite
- use tracing or dump features without this noise
- debug CC without this noise
