The `simpleBind` function exposed by V8 Extras was initially added to
work around the terrible performance of `Function.prototype.bind` at
the time. Nowadays `Function.prototype.bind` is significantly faster
and fully optimized by TurboFan, however, so there’s no need for the
`simpleBind` helper anymore.

This will allow V8 extra consumers to track promise state without
using a side-table. This is used by streams as of
173f9f67be.

This function was only needed for extrasUtils. Since it was simply
calling a builtin function, just expose that builtin instead. This
requires an arguments adapter frame for the builtin. As a drive-by
fix, also added an arguments adapter for the extrasUtils.resolvePromise
(and a regression test).
Other cleanup: removed unused native context slot for PROMISE_SET_AND_CREATE.

https://codereview.chromium.org/1343113003 introduced a separate InternalPackedArray constructor to the extras utils object, distinct from the one used by natives. However, it omitted the code to set up the methods for that InternalPackedArray. This makes all the basic manipulation methods available.

This adds a utils object meant specifically for V8 extras, presenting a limited
API surface for doing things that would otherwise require %-functions.

The alternative of passing an object template at context creation is
unfeasible because we need a context to instantiate the template.
At the time we create the context from snapshot or bootstrap from
scratch, we would already need that template instance, leading to a
chicken-and-egg problem.
This is an alternative that is simpler and less intrusive.

For the moment, we only pass the global object (the one we are setting up).
A few smaller changes were necessary to avoid failures in
test-object-observe/DontLeakContextOnObserve. Otherwise the global object
would be retained by being context allocated, leading to test failure.

Exposed to the extras as extrasExports (on the builtins object), on
which they can put things that should be accessible from C++. Exposed
to C++ through the V8 API as v8::Context::GetExtrasExportsObject().
Adding a test (in test-api.cc) required adding a simple extra,
test-extra.js, which we build into the standalone builds.
