This implements the proposal from #124512. For that it contains the following changes: * Remove the global override of `new`/`delete` when `WITH_CXX_GUARDEDALLOC` was enabled. * Always use `MEM_CXX_CLASS_ALLOC_FUNCS` where it is currently used. This used to be guarded by `WITH_CXX_GUARDEDALLOC` in some but not all cases. This means that a few classes which didn't use our guarded allocator by default before, are now using it.
