[api-minor] Remove the normalizeWhitespace option in the PDFPageProxy.{getTextContent, streamTextContent} methods (issue 14519, PR 14428 follow-up)

With these changes, we'll now *always* replace all whitespaces with standard spaces (0x20). This behaviour is already, since many years, the default in both the viewer and the browser-tests.
