Windows accessibility clients talk directly to the content process via COM.
In order to expose an OOP iframe document accessible as a child of the embedder iframe accessible via COM, the embedder process needs a COM proxy for the iframe document accessible.
This is exposed on the embedder's BrowserBridgeChild, so we can use this when a client asks for the child of the OuterDocAccessible.

For an out-of-process iframe, we need to be able to return a remote embedder accessible as a child of an OuterDocAccessible.
For parent process OuterDocAccessibles, we use the ProxyAccessible for the embedded document.
In the case of out-of-process iframes, there is no ProxyAccessible for the embedded document, since the iframe is in a content process and ProxyAccessibles only exist in the parent process.
Like ProxyAccessibleWrap, the only real method that gets called is GetNativeInterface, which returns a COM proxy for the document.

PresShell::EventHandler::HandleEventWithCurrentEventInfo is the only possible
place will do such handling; other places pass either a nullptr or a
non-MouseDown/Up event.

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.

We do this when the OuterDocAccessible is constructed.
This will be used later in the parent process to link the trees together when the iframe's embedded document accessible is added.

Supporting out-of-process iframes requires us to hold onto a DocAccessibleParent in BrowserBridgeParent.
However, we can't guarantee the order of cleanup between the two content processes.
Therefore, we need reference counting to kee the object alive.

Accessibles can be shut down twice. For example, their doc might shut
them down in its own ShutDown, while a reference is still being held by
a dispatched event. When the event goes away, or the cycle collector
kicks in, the accessible may be finally released and shut down again via
LastRelease.

If the DOM focus is removed before something else is focused, the document gets DOM focus, but no blur event is fired (bug 559561).
This means that no a11y focus event is fired, so clients aren't notified.
This is particularly problematic for screen readers when dismissing some ARIA dialogs, as the screen reader doesn't know that focus has returned to the top level document.

This commit moves the actual implementation of nsIRemoteTab from BrowserParent

This commit removes nsIRemoteTab as a parent class from BrowserParent,
so that BrowserHost is the only concrete implementation of nsIRemoteTab.
Some static_cast's are updated to cast to BrowserHost, and other places
have to be updated to pass a BrowserHost instead of a BrowserParent.
WindowGlobalParent had a getter to return it's managing BrowserParent
as a nsIRemoteTab. I couldn't find a use of this in-tree, so I've just
opt-ed to remove it. If there's a use-case, we can add something back
in.

`nsIPresShell::ScrollAxis` can be used anywhere and it's used by some
utils actually. So, it should be in `mozilla` namespace and perhaps,
`PresShellForwards.h` is a good place to move it rather than creating
new header file.

We're going to stop propagating these flushes up since they're not observable by
content and it matches what would happen in a fission world.
This test relies on the parent document layout tree being up-to-date by the time
we run the iframe load handler. Also improve diagnostics in the case the
assertion fails.

Per the discussion in:
https://groups.google.com/d/msg/mozilla.dev.platform/P79pwa9z5m8/iPYPAWPHCAAJ
They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.

This patch moves some `enum` in `nsIPresShell` which are in public scope into
`mozilla` namespace and change them as `enum class`es.
Unfortunately, only "where to scroll" enum is just defines constants of
percentages of scroll destination. Therefore, this patch makes only them
as `static const`.
