Drop the OUString vs. OUStringLiteral comparison operator overloads

...which can be subsumed by their OUString vs. OUString counterparts now that
conversion from OUStringLiteral to OUString is cheap since
e6dfaf9f44f9939abc338c83b3024108431d0f69 "Turn OUStringLiteral into a
consteval'ed, static-refcound rtl_uString".  (The only place that needed
adaption was the dubious use of temporary OUStringLiteral instances in
sal/qa/rtl/strings/test_oustring_stringliterals.cxx, which now caused "error:
conversion function from 'rtlunittest::OUStringLiteral<6>' to
'const rtlunittest::OUString' invokes a deleted function".)
