Inspired by <https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607102.html> "[PATCH] doc: -Wdelete-non-virtual-dtor supersedes -Wnon-virtual-dtor", drop explicitly enabling -Wnon-virtual-dtor in favor of -Wdelete-non-virtual-dtor, which is already enabled by -Wall. (-Wdelete-non-virtual-dtor first appeared in Clang 3.0, <https://github.com/llvm/llvm-project/commit/8bd428574c717e68a8274739d2ba0f6dc16fd0fb> "Add new warning that warns when invoking 'delete' on a polymorphic, non-final, class without a virtual destructor", and GCC 4.7, <https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=014ab419efc12a59efebd2720d79e1c055675c85> "invoke.texi: Document -Wdelete-non-virtual-dtor. [...]") Dropping the explicit setting of -Wnon-virtual-dtor (and nowhere setting it implicitly via -Weffc++) means we can get rid of lots of places that either set -Wno-non-virtual-dtor or use some pragma to ignore -Wnon-virtual-dtor. (In various places across extensions/source/activex/ and winaccessibility/, the commits f26996bd3398afa789a5491968244563ccf70908 "Silence -Werror,-Wnon-virtual-dtor in generated so_activex.h (clang-cl)" and c6086ca6535692496fbd718d174d8eb5a5dea7c7 "Silence -Werror,-Wnon-virtual-dtor in generated UAccCOM.h (clang-cl)" had singled out some includes to wrap them in pragmas. Now that those pragmas are gone again, move those includes back to where they had been prior to being singled out. And the -Wno-non-virtual-dtor in external/firebird/macos-arm64.patch.0 appeared first in ccd0e5f445d4a7d0e7aca6c23c02c61bf14510b2 "Make firebird build for macOS on arm64", which, though it doesn't state it explicitly, apparently created that patch's builds/posix/prefix.darwin_arm64 as a copy of firebird's already existing builds/posix/prefix.* files, which routinely include that warning option too, so keep it there too even if it is probably irrelevant throughout.)

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.
