QDoc: Drop default arguments from some \fn documentation strings

In the \fn commands for a limited number of methods in the
documentation for Testlib and Widgets, `= 0` is passed as default
argument instead of `= Qt::KeyboardModifiers()`. Until QDoc with Clang
17, inclusive, QDoc generated the correct signature. However, with
Clang 18, QDoc outputs `= 0` in the documentation. While strictly
speaking still correct, this change impacts the documentation
negatively in terms of readability.

Dropping the default argument from the \fn command ensures that QDoc
generates the right signature with both Clang 17 and Clang 18.

Task-number: QTBUG-123130
Pick-to: 6.7
