Improving the analyzer to not flag a warning about init-only properties that are actually constructor parameters. In particular, record types with positional parameters desugar to classes with both a constructor and init-only properties (eg, to support "with" expressions). Since these properties are deserialized via the constructor and not the property setter, they support the fast path and round trip just fine, so the diagonstic analyzer should not raise the SYSLIB1037 warning. Issue 58770
Edit to fix missing semi colon in unit test's CreateCompiliation string Issue 58770
