Clean up SvxChartColorTable

* nNextElementNumber is unused since d57dfa29c2ba47293eb12a853cdccf4196565ef7
  "Improvement of adding and removing color charts".

* There appears to be no compelling reason to store sDefaultNamePre-/Postfix as
  members (but which are not even copied by the copy ctor).  Just compute them
  whenever they are needed in getDefaultName (which is understood to not be a
  hot code path).

* With those changes, the user-provided default and copy ctor can be left
  implicitly-declared, which avoids -Wdeprecated-copy (because the copy
  assignment op was implicitly-declared while the copy ctor was not) with GCC
  trunk towards GCC 9.
