Convert the line endings manually since the parser is sensitive to the trailing whitespace (the writing of the file will create a `\r\n` rather than `\n`). This largely fixes the issues for Windows with the issue that the processing of the file location is currently not properly processing escape characters and results in issues. In theory, it should be possible for `getStringLiteralIfNotInterpolated` to process the literal segments with `getEncodedStringSegment` for each segment and then return a literal value cooked. However, doing so will require that the function return a `std::string` rather than `StringRef` since the cooking means that we cannot simply provide a reference to the SourceManager view.
