QtCore: mark some operations nothrow

This shotgun-surgery approach is motivated by trying to get a
clean(er) build for -Wnoexcept on GCC, so it is expected that
for any class touched here, there will be more operations that
can be marked nothrow. But they don't show up in conditional
noexcept clauses, yet, so they are deferred to some later
commit.
