Include SwiftSyntaxCDataTypes.h in snapshot binary

The PR swiftlang/swift#39441 has split the SwiftSyntaxParser.h into two parts - 
* SwiftSyntaxCDataTypes.h
* SwiftSyntaxParser.h

The generated snapshot binaries are missing `SwiftSyntaxCDataTypes.h` header.  This is causing a build failure for a sample using SwiftSyntax on Windows.
