Display.withCrLf() is producing wrong line breaks on Windows

[Christopher-Hermann]

Describe the bug
Display.withCrLf() is producing wrong line breaks based on the heuristics in the Windows implementation. This happens only for Strings that contains broken formatting itself. But nevertheless, I think we can fix this issue by improving the method implementation.

To Reproduce
See Test case

	@Test
	public void testMixedLfAndCrflOnWindows() {
		if (!SWT.getPlatform().equals("win32")) {
			return;
		}

		String act = Display.withCrLf("First Line \n second line \r\n third line");

		assertEquals("First Line \r\n second line \r\n third line", act);
	}

Expected behavior
Expectation is that the method replaces all standalone \n with \r\n.
With the given example, \r\n results in \r\r\n

Screenshots
If applicable, add screenshots to help explain your problem.

Environment:

1. Select the platform(s) on which the behavior is seen:

• • All OS
• • Windows
• • Linux
• • macOS

Just assigned it to you, but you can of course also work on an issue even if it hasn't been assigned to you :)
Just leave a note that you are working on it to avoid concurrent work.
