[MSPAINT] Use CF_DIB instead of CF_BITMAP (#5349)

Browse source 
CF_BITMAP is not recommended format for copying. In fact, Win10 won't accept it.
- Use CF_DIB clipboard format instead of CF_BITMAP in copying.
- Use CF_ENHMETAFILE, CF_DIB, or CF_BITMAP in pasting.
- Add BitmapToClipboardDIB, BitmapFromClipboardDIB, and BitmapFromHEMF helper functions to dib.cpp.
- Re-enable paste by fixing the bug that is embugged in the previous commit.
- Enable Cut, Copy, Paste, and Delete on text editing box by modifying OnInitMenuPopup.
- Add IDS_CANTPASTE resource string to show message on paste failure.
