Merge 107170 - DOM mutations should not be delivered on worker threads

Merge 107170 - DOM mutations should not be delivered on worker threads
https://bugs.webkit.org/show_bug.cgi?id=77898

Reviewed by Dmitry Titov.

Source/WebCore:

In V8RecursionScope, only call WebKitMutationObserver::deliverAllMutations
if in a Document context.

This is accomplished through a change to V8Proxy::instrumentedCallFunction
(which now takes a Frame* instead of a Page*), requiring an update to all
callers of that function (accounting for the majority of files changed
in this patch).

Added ASSERT(isMainThread()) in a deliverAllMutations to confirm that
it's no longer called on worker threads, and in enqueueMutationRecord,
where the same global store of active observers is accessed.

See also http://crbug.com/112586, where the problem was initially
reported.
