[test] Remove module pragma in favor of .mjs d8 treats files with the .mjs extension as modules instead of classic scripts. Thus, the `// MODULE` pragma and its corresponding logic in test runners can be removed in favor of explicitly adding the extension.

Replace %RunMicrotasks with %PerformMicrotaskCheckpoint This replaces Runtime_RunMicrotasks with Runtime_PerformMicrotaskCheckpoint. RunMicrotasks forcibly runs Microtasks even when the microtasks are suppressed, and may causes nested Microtasks in a problematic way. E.g. that confuses v8::MicrotasksScope::IsRunningMicrotasks() and GetEnteredOrMicrotaskContext(). OTOH, PerformMicrotaskCheckpoint() doesn't run cause the failure as it respects the microtask suppressions. As all existing tests don't call RunMicrotasks() in the suppressed situation (like Promise.resolve().then(()=>{%RunMicrotasks();})), this change should not affect to these tests.
