Slightly optimize WebCore microtask execution
https://bugs.webkit.org/show_bug.cgi?id=289030
rdar://146070011
Reviewed by Ryosuke Niwa.
WebCore microtask execution is wrapping it with so many unnecessary
abstractions. And it is causing massive slowdown compared to simple
execution in JSC's default implementation.
1. We increase inline capacity of EventLoop Tasks to avoid repeated
small allocations and deallocations.
2. We remove JSMicrotaskCallback and use JSC::Microtask directly.
