build: let meson add compiler flags for libstdc++ assertions

We have manually enabled libstdc++ assertions since cl/797. Meson 1.4.0
(the minimum version we mandate) enables this by default, so we can
remove the enabling compiler flag from the list of project arguments.

With this patch, `-D_GLIBCXX_ASSERTIONS=1` is still present in the
compile command logs when building with both gccStdenv and clangStdenv.
