QString:add (last)indexOf overload with QRegularExpressionMatch output

This patch adds indexOf and lastIndexOf with QRegularExpressionMatch
output overloads to QString. This allows to get the match corresponding
to the index returned.

[ChangeLog][QtCore][QString] Added support for retrieving the
QRegularExpressionMatch to indexOf and lastIndexOf.
