Fix #11342
Fix selection after focus-in by mouse in QgsFilterLineEdit

After focusing a QgsFilterLineEdit with the mouse, the end of the selection was
"attached" to the end of the content.
This was caused by overwriting Qt's mousePressEvent, that is responsible for
handling the selection without handing back the responsibility after the focus
in event was finished.
