NOTE: There are targets that still do not support the debug entry values production.
NOTE: There are targets that still do not support the debug entry values production and that is being controlled with the SupportsDebugEntryValues.
In addition, SCE debugger does not have the feature implemented, so prefer not to emit the debug entry values in that case. The EnableDebugEntryValues can be used for the testing purposes.
