The macro was unconditionally defined since
44a7412795 and, despite being named like
a public Qt macro, never documented, so just remove it.
Also means we can remove the ODR protection from end() and cend() now.
[ChangeLog][Potentially Source-Incompatible Changes] The undocumented
Q_STRINGTOKENIZER_USE_SENTINEL macro was removed. It was
unconditionally defined since Qt 6.0.
