QDebug: pretty-print QStrings and QStringRefs

[ChangeLog][QtCore][QDebug] Printing of QStrings and QStringRefs
whenever "noquote" is not active now prints the strings in a format that
can be copied back to C++ code. All characters that aren't printable in
US-ASCII are escaped (this includes printable Unicode characters outside
of US-ASCII). Pretty-printing will not respect QTextFormat padding or
field widths.
