fix(3p/nix): allocate the vSourceExpr via uncollectable memory r/1352
Previously the memory would occasionally be collected during eval since the GC doesn't consider the member variable as alive / doesn't scan the region of memory where the pointer lives. By using the traceable_allocator<T> allocator provided by Boehm GC we can ensure the memory isn't collected. It should be properly freed when SourceExprCommand goes out of scope.
