Enable -Wdeprecated-copy-dtor where available
We already get -Wdeprecated-copy (warning about implicitly defined copy
functions that will in the future be deleted because other user-provided copy
functions exist) automatically through -Wextra, where available.
-Wdeprecated-copy-dtor (warning about implicitly defined copy functions that
will in the future be deleted because of a user-provided dtor) is split off
into its own warning excluded from -Wextra for somewhat unclear reasons, see the
discussion at <https://gcc.gnu.org/bugzilla/buglist.cgi?quicksearch=88136>
"-Wdeprecated-copy is draconian and shouldn't be in -Wall".
But -Wdeprecated-copy-dtor has been useful in finding issues (esp. the Clang 10
trunk version, which, unlike the GCC 9 version, also finds copy functions that
are implicitly defined because they are used from template instantiations), see
3e59716375a240576fd6d8759b32b4319506ed70 "Prevent
BroadcastRecalcOnRefMoveHandler copies" and
4f98cd0f9ce9c2a331a5d34b3ef9d18f9bb6b235 "ScShapeChild has broken copy
functions".
We need to disable -Wdeprecated-copy-dtor in files included from external/boost,
and in two compilerplugin/clang/test/ files.
