Subject: [PATCH] Eradicate QT_STRINGVIEW_LEVEL

It was designed to gauge the impact of replacing QString functions
with QStringView ones, as opposed to just overloading, but that never
came to pass, for two reasons:

1. We never got to implement a full set of overloads with the pattern
   in a large enough library (QtCore) for results to matter.

2. QStringView doesn't accept everything that QString accepts, making
   it unsuitable as a drop-in replacement (QAnyStringView has that
   property, though, but we never added a QT_ANYSTRINGVIEW_LEVEL
   macro).

So, R.I.P. QT_STRINGVIEW_LEVEL.
