QStringView: add converting constructor from array-like containers

Centralize, rather than keeping adding constructors from any
array-like container.

A more robust implementation, likely following the converting
constructor for std::span ([span.cons]), is out of scope for C++17
and will require C++20's ranges and concepts.

[ChangeLog][QtCore][QStringView] QStringView can now be constructed
from any contiguous container, as long as they hold string-like data.
For instance, it's now possible to create a QStringView object
from a std::vector<char16_t>, a QVarLengthArray<ushort> and so on.
