RenderFrame is a very poor name for what this class does. RemoteLayerTreeOwner
isn't perfect (it's not the only thing that owns layer trees), but it's
hopefully clearer.

This patch makes several changes to the kinds of URLs where we can cancel
content JS when navigating between them:
1) When navigating directly to a URL (e.g. by typing something into the
location bar and hitting Enter), we allow canceling content JS if the URLs
differ in any way *except* their ref ("#"). To help with this, we also
attempt to fix up the URL (e.g. by prepending "http://" to it).
2) When navigating through history, we allow canceling content JS if the
`prePath` part of the URLs differ. Most notably, this allows canceling
content JS when one of the URLs is an `about:` page (e.g. when hitting the
Home button).
3) We explicitly disallow cancelling content JS if the currently-running JS
is trusted or if the page being navigated away from is anything but
http(s): or file:.
4) We also disallow cancelling content JS for windows that are still being
created (e.g. when creating a new tab or window via `window.open`). For
more background on this, see the comments about `mCreatingWindow` in
dom/ipc/BrowserParent.h.
5) We ensure that, when attempting to cancel JS, the tab ID of the
currently-running script matches the original tab that requested the
cancellation. This avoids a race condition in which a particular JSContext
has already moved on to executing another tab's JS by the time we hit our
interrupt callback.

If window emulation is enabled, an out-of-process iframe document should use the same emulated window as its embedder.
Previously, we were setting this on DocAccessibleParent, but we weren't sending it to content to make it available on DocAccessibleChild.
This meant that accessibles in out-of-process iframe documents were reporting the wrong window handle.

It must be possible to retrieve any accessible by calling IAccessible::accChild on the RootAccessible (in the parent process) with the unique id of the desired accessible.
Among other things, this is the way accessibility events are targeted on Windows.
Previously, this code only searched remote documents at the top level of the tree.
In order to support out-of-process iframes, it must now also search embedded documents at the top level of their content process.
As part of this, the MSAA id must be set for out-of-process iframe documents, just as it is for top level documents.
This was already being sent from the content process, but previously, we didn't store this in the parent process.

Aside from the parent being needed by the client, this is also important because events from the embedded document are deferred until the parent COM proxy is received.
As part of this, we no longer try to send the parent COM proxy during construction of an OuterDocAccessible in the parent process.
This was previously a no-op anyway, as DocAccessibleParent::SendParentCOMProxy called DocAccessible::GetAccessible for the frame element, which would have returned null because the accessible isn't bound to the document until *after* it is constructed.
Changing this to directly pass the OuterDocAccessible was causing assertions in content processes, since it sometimes meant the parent COM proxy was sent twice, which is precisely what the assertion is protecting against.
Instead, the parent proxy is sent in Browserparent::RecvPDocAccessibleConstructor as it always was.

DocAccessibleParent already has IsTopLevel(), which identifies a document at the top level of the hierarchy; i.e. it has no parents.
Now that we have out-of-process iframes, we need to be able to identify and retrieve documents at the top level of their content process, even if they are embedded by another remote document.
DocAccessibleParent::IsTopLevelInContentProcess() has been introduced to achieve this.
BrowserParent::GetTopLevelDocAccessible() now uses this instead of IsTopLevel(), since we want to be able to get the top DocAccessibleParent even for a BrowserParent for an out-of-process iframe.

Currently, BrowserChild rendering is enabled and disabled by `RecvRenderLayers`, and this
method is called only by the tab switching code.
This commit does several things.
1. It factors out the code to enable/disable rendering to MakeVisible/MakeHidden so it can
be used outside of `RecvRenderLayers`
2. We track the current value of RenderLayers and use it in conjunction with EffectsInfo to
determine if we need to be rendering at any given moment
3. We only apply RenderLayers to the root OOP browser (not OOP-iframes)
These changes together make it so that BrowserChild will render IFF 'visible' || 'renderLayers',
and will only apply 'renderLayers' to the root browser.

This commit adds two small fixes to make the OOP-iframe code more robust.
The first fixes a crash during shutdown for a tab that has OOP-iframes. It's
possible for the BrowserBridgeParent's to be shutdown before the root
BrowserParent. In this case, SetOwnerElement will run for the root BrowserParent,
but the child BrowserBridgeParent's will not have BrowserParent actors.
The second hooks up the BrowserBridgeParent constructor to actually use

For iframes in a different process to their embedder, when the embedded iframe content process tells the parent process about the iframe document, it does not have the actor for the parent document accessible, nor does it know the accessible id of the embedding iframe.
However, the embedder will have previously sendt the actor and id for the embedder accessible to the parent via PBrowserBridge, so we can use that to identify the parent accessible.
