The use of makeTransferable on all AbortSignal instances made creating them always slow, causing bottlenecks in stuff like Web Streams. This refactors that so that AbortSignals are not transferable by default, which is actually the correct standard behavior anyway. A new transferableAbortSignal and transferableAbortController utility is provided to enable the transferable use case. Signed-off-by: James M Snell <[email protected]>

Suggested change
| functioncreateAbortSignal(init){ | |
| functioncreateAbortSignal(init=kEmptyObject){ |
and then requiring kEmptyObject from internal/util will probably fix the test failures. You might also want to rebase to include the change from #43159 for this to work.
