[NFC]add initialization for EmitCompactUnwindNonCanonical in ctor

[ChengChen002]

Summary

I found that the newly added member variables, "EmitCompactUnwindNonCanonical" were not initialized in the constructor, but other member variables were initialized. The behavior seems to need to be consistent to improve code.
