Summary:
This adds a new jsi API prepareJavaScript. This accepts the same
parameters as evaluateJavaScript() but does not evaluate anything; instead
it returns a new object PreparedJavaScript which can itself be evaluated,
via the new API evaluatePreparedJavaScript().
There is a new empty class PreparedJavaScript which may be subclassed by
each Runtime variant to store its particular prepared form.

Summary:
This changes jsi::evaluateJavaScript() to accept a
const shared_ptr<Buffer> & instead of a unique_ptr<Buffer.
It is reasonable to want to pass the same buffer to evaluateJavaScript()
multiple times. This will also help unify the API with the upcoming
prepareJavaScript() API.
Because shared_ptr has a unique_ptr constructor, this is compatible with
all call sites.

This check is too aggressive. We will consider putting it back once we are

Summary:
In the version of JSC on iOS 11, creating a JSContext on one
thread and using it on another can trigger subtle and nearly
impossible to debug reentrancy-related crashes in the VM (see
https://bugs.webkit.org/show_bug.cgi?id=186827). In !NDEBUG builds,
check for this case and throw an exception, so it can be detected
early.

Summary:
Older versions of JSC (ios 11 and before) have a bug which I
believe the ProtectionQueue mechanism tickles:
https://bugs.webkit.org/show_bug.cgi?id=186827
This removes the ProtectionQueue and replaces it with an atomic flag
to avoid calling unprotect after VM shutdown.
This also fixes a race condition in shutdown.
