Fixes #1250
OrderedImportsonly recognized.newlinestrivia when reconstructing lines. SwiftSyntax represents Windows line endings as.carriageReturnLineFeeds, so CRLF separators were kept as trivia and could produce extra blank lines when imports were reordered.This change treats LF, CR, and CRLF trivia as line boundaries and adds a regression test using CRLF input.
