Implement date-time fromString(QStringView...) methods

Inline the QString versions. One const QString & variant remains in
each case: the date-time parser keeps a copy of the string it's been
given, so the methods calling it have a hybrid method taking the
string as the text to parse along with a view as the format. This
avoids copying the string when the caller has an actual QString to
pass in; the version with QStringView for both parameters has to
toString() the text to be parsed, at some point on the way into the
parser, but we can avoid that in the QString-accepting ones.
