qmldom: Start of the Qml Dom library

The goal of the Dom library is to provide a nicer to use basis for the
Qml Code model, to be used by the various QML tools, the designer and
the new compiler.

This commit just adds some common utilities used by the library, to
output strings to a Sink, i.e. a function<void(QStringView).
This allows writing without allocations of extra temporary strings.
The more interesting parts are added in subsequent commits
