Fix Dynamic Profile info on macOS and Linux

- Dynamic profile (DPL) was #ifdef'd out when CC was ported to linux
- DPL is intended for testing
- DPL can store profiling info from the interpreter in a file
- DPL can then be loaded on a future run for use by the jit
- Dynopogo CI on macOS + Unix was trying to load DPL that didn't exist
- It would try multiple times, this added ~2 seconds to every test
- Fixing this therefore makes tests much faster
- Fix was:
   a) enable in CommmonDefines
   b) Fix a compiler error in ScriptContextProfiler AND
   c) Change a condition so the Uninitalize method is called
