Improve loplugin:stringview

Issue the "instead of O[U]String, pass [u16]string_view" diagnostic also for
operator call arguments.  (The "rather than copy, pass subView()" diagnostic is
already part of handleSubExprThatCouldBeView, so no need to repeat it explicitly
for operator call arguments.)

(And many call sites don't even require an explicit [u16]string_view, esp. with
the recent ad48b2b02f83eed41fb1eb8d16de7e804156fcf1 "Optimized OString operator
+= overloads".  Just some test code in sal/qa/ that explicitly tests the
O[U]String functionality had to be excluded.)
