Refactor wildcard support in QRegularExpression

The API originally proposed was flawed in the sense that the setter
function would use a modified version of the parameter given which would
have make it a black box for the user. This patch fixes that by removing
that setter and providing a static method that will return the pattern
suitably modified to be used by QRegularExpression the same way the
escape method does.

[ChangeLog][Core][QRegularExpression] Implemented support for wildcard
patterns through a static method.
