Implement exact match expression builder for QRegularExpression

QRegularExpression doesn't offer a direct equivalent of QRegExp's exact
match.

There are several places in the Qt sources that use this feature. This
patch implements a small helper function that builds the expression as
recommended in the documentation and updates the related code.

[ChangeLog][Core][Tools] QRegularExpression now provides
anchoredPattern() which is a helper function to build regular
expressions used for exact matching.
