script: stub AbortSignal (#37033)
This is a stub for `AbortSignal`, which we would like to merge first in order to work in parallel on https://github.com/servo/servo/issues/34866, and perhaps also https://github.com/servo/servo/issues/36936 --------- Signed-off-by: gterzian <2792687+gterzian@users.noreply.github.com> Signed-off-by: Taym Haddadi <haddadi.taym@gmail.com> Co-authored-by: Taym Haddadi <haddadi.taym@gmail.com>
