FIX(cmake): Set QT_RESTRICTED_CAST_FROM_ASCII

With the old qmake buildsystem we used to set QT_NO_CAST_FROM_ASCII (for
the Mumble client) in order to avoid problems with character encodings
in our Strings. This was not done in the new cmake system yet.

Instead of the aforementioned macro, this commit sets (for all targets)
QT_RESTRICTED_CAST_FROM_ASCII instead in order to be able to
automatically convert direct String literals to QString as these usually
don't contain any problematic characters (non-ASCII) in the first place.
And this allows to e.g. compare a QString against a String literal or do
something like
QString myString = "This is a test";
which we know to be unproblematic.

Note however that (quote from Qt's docs)
"Using this macro together with source strings outside the 7-bit range,
non-literals, or literals with embedded NUL characters is undefined."
