Remove OUStringBuffer member function overloads for OUStringLiteral

...which are already adequately covered by overloads for OUString and the
OUStringLiteral-to-OUString implicit conversion that became cheap in
e6dfaf9f44f9939abc338c83b3024108431d0f69 "Turn OUStringLiteral into a
consteval'ed, static-refcound rtl_uString".

The only place where the removal of the ctor overload caused an issue for copy-
initialization (in sfx2/source/appl/newhelp.cxx) could easily be rewritten using
direct-initialization.
