Remove @newPromiseCapability
https://bugs.webkit.org/show_bug.cgi?id=321999
rdar://185184613
Reviewed by Yijia Huang.
Let's just use `@newPromise` and
@rejectPromiseWithFirstResolvingFunctionCallCheck etc. that is much more
efficient (not allocating an object for a tuple), not doing any property
lookup. As a result, nobody is using @newPromiseCapability anymore. So
this patch removes it from builtin JS.
