Qt pdf display control based on pdfium
No dependence
Compile with vs2019, Qt5.15.2

Fork from qt-lbas/qtpdf The following changes can also be made:
- Use cmake instead
- Fixed pdfium version to avoid compilation problems caused by pdfium upgrade
- Combine QtPdf and QtWidgets
- Remove the relevant code of the qt module, modify the name of the generated file to qpdf, to avoid the same name as the file in the Qt SDK
