[JSC] Apply Promise.try spec
change
https://bugs.webkit.org/show_bug.cgi?id=321890
rdar://185064567
Reviewed by Sosuke Suzuki.
Test262 is updated[1] to include the latest spec change proposal
for Promise.try[2], which uses PromiseResolve instead of a promise
created by NewPromiseCapability. This simplifies our Promise.try
implementation since we can just use @promiseResolve and @promiseReject
helpers instead. Also this removes the reference to
@newPromiseCapability in JSC code. So we drop PromiseOperations.js and
its JS builtins, and replace @newPromiseCapability with C++ version for
remaining WebCore users.
WebCore users can be replaced by using normal Promise + first-resolving
handler. This is fixed in a subsequent change.
