This is essentially equal to restoring cached children and removing
current children from a BrowsingContext, which is the correct
behaviour. It would've been better if the current children were
removed in a more transparent manner, but it is more important to
remove an assert that too eagerly triggers.

Previously the `WebNavigationChild` would keep track of when triggering its
`nsIWebNavigation`, `goForward`, `goBack`, `gotoIndex`, and `loadURI` methods.
It's `nsIWebNavigation` instance is always an `nsIDocShell` and as part of
porting `OnStateChange` and `OnLocationChange` events from
`WebProgressChild`/`RemoteWebProgress` to `BrowserChild`/`BrowserParent`, this
informations needs to be available from the `BrowserChild`. As it stands, it is
currently an expando property on the `WebProgressChild`.
Instead of introducing yet another XPCOM interface for the WebProgressChild, we
now store this information directly on the `nsDocShell`. Furthermore, instead
of having the `WebNavigationChild` manage this part of the `nsDocShell`'s
state, we can have the `nsDocShell` manage this state itself so it is always
consistent.

We were incorrectly not performing an EnsureSubscribed for the origin
process which a BrowsingContext came from. Normally this would mean that
the BrowsingContext could die in the parent process before the
WindowGlobalParent listener arrived, but that didn't generally happen
due to the low likelihood of a CC occuring between the two messages.
It's likely that this crash was caused by people on lower-end hardware
triggering a print. This would be a longer-running operation in the
content process between the first and second message than usual. On
systems with memory pressure, there would be a higher chance of a CC
occuring between the messages, which would then cause this crash.
This patch correctly connects the origin ContentParent to the
BrowsingContextGroup, which will prevent the CC from destroying our
objects.
In the future, it may be desirable to ensure that this doesn't happen
more reliably by using a ContentParent-local table for looking up
BrowsingContext IDs sent over IPC. This would prevent our current
dependency on the weak pointer behaviour of the current global ID cache.
Unfortunately, this patch adds no tests, and I'm not aware of a good way
to test this edge case to confirm it has been fixed. I believe that this
patch should fix the issue I mention, however.

Per the discussion in:

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`.

Next, we should mark `PresShell::ScrollContentIntoView()` as
`MOZ_CAN_RUN_SCRIPT` because it's used widely.
This patch marks its `PresShell` users, `GoToAnchor()` and `ScrollToAnchor()`,
as `MOZ_CAN_RUN_SCRIPT`. Additionally, this patch moves them from
`nsIPresShell` to `PresShell` because all callers refers `PresShell` directly.

Similarly to nsITabParent, TabChild is exposed to frontend code via nsITabChild. It's not clear what the future of this interface will be, but for now we can just rename it to nsIBrowserChild.

nsITabParent is exposed to frontend code and is generally used as a representation of a remote tab. We could just rename the interface to nsIBrowserParent and worry about it later, but I think it's better to rename the interface to nsIRemoteTab so that we can later work on splitting the interface away from the PBrowser protocol.
Note: Some frontend code refers to a TabParentId. This commit renames this to RemoteTabId. We need to figure out the purpose of TabId with fission.
