[JSC] Update import-defer implementation based on the proposal update
https://bugs.webkit.org/show_bug.cgi?id=321369
rdar://184423667
Reviewed by Sosuke Suzuki.
After 313139@main implemented import-defer, the proposal fixed several
bugs. This patch applies these fixes.
1. https://github.com/tc39/proposal-defer-import-eval/pull/85
Consider SCC status when deciding to short circuit on ReadyForSyncExecution
and GatherAsynchronousTransitiveDependencies
2. https://github.com/tc39/proposal-defer-import-eval/pull/87
(1) introduced an assertion inconsistency, and the PR fixes it.
