Add QtPdf to cmake build

Port QtPdf to Qt6:

  * QtPdf,QtPdfWidgets,QtPdfQuick libs
  * QtPdfQuickPlugin, QtPdfPlugin (imageformat) plugins
  * widget and quick examples
  * qtpdf tests

To fit gn cmake integration and new repo layout code is a bit
reshuffled.

Compared to qmke build following features are not ported yet:

  * ios fat libs
  * qtbase 3rdparty static dependencies

WebEngine build can be skipped with setting
QT_FEATURE_qtwebengine_build=OFF

Note this patch needs follow up for 6.2 branch to disable qtpdf
builds by default, since this should not part of qt 6.2 release.

Pick-to: 6.2
Task-number: QTBUG-95353
