[Octave Backend] Port QRegExp to QRegularExpression
Port QRegExp::exactMatch() by making the QRegularExpression pattern anchored.
QRE::anchoredPattern() was introduced with Qt 5.12 and cantor has min. required Qt version set at 5.8; thus anchor the pattern with ^ and $.
Also since we're doing nothing with the capture group, make it non-capturing (?:).
All unit tests pass, except for testlua (fails on master too), and testworksheet which hangs (on master too).
