[JSC] Implement Promise.try
https://bugs.webkit.org/show_bug.cgi?id=269775
Reviewed by Justin Michaud.
This patch implements https://github.com/tc39/proposal-promise-try behind a
runtime option;
the proposal is currently at Stage 2 but the spec is very simple and not
expected to change.
Effectively, Promise.try(f) is a more convenient way to write `new
Promise((resolve) => { resolve(f()); })` --
we don't care whether f is sync or async, but if is synchronous, we want it to
be executed immediately.
This implementation includes
https://github.com/tc39/proposal-promise-try/pull/16, which the champion
expects to merge;
it simply extends the API to Promise.try(f, ...args) such that arguments can be
forwarded to the callback.
