Fix memory corruption if task is launched inside finalizer
In #48919, the tid selection logic inside `enq_task` gained a `!GC.in_finalizer()` condition. However, this made it possible for `workqueue_at` to be reached with `tid==0`, which would attempt and out-of-bounds write under `@inbounds`, corrupting memory. This was not caught in the test suite despite `--check-bounds=yes`, because our `--check-bounds=yes` is currently best effort. That would be fixed by #50239, which exposed this bug.
