Both the deprecated `Screen.lockOrientation` and replacement
`ScreenOrientation.lock` APIs have been updated to make use of a new
`OrientationLock` field on the `BrowsingContext`. This replaces the
storage and use of APIs for this on the root docshell.
In the non fission case things should behave the same, as pending
promises for previous calls to `Screen.lockOrientation` will still be
cancelled in process. If there are `BrowsingContext`s in other
processes though, IPC will be sent to the parent, and then each other
child to cancel them. This should be spec compliant as the spec is
already racy with regards to multiple `lockOrientation` calls.
This new implementation has a little extra IPC than the optimal
implementation would since the root `BrowsingContext`s
`OrientationLock` is set using the normal `SyncedContext` machinery,
rather than combining the `AbortOtherOrientationPendingPromises`
message for a single message.
This commit fixes both Bug 1597413 and Bug 1597443.

We need it to live in BrowsingContext instead of WindowContext, because
we need to preserve the zoom level across same-origin navigation.
It'd be nice if it only lived in the top BC, but that's not possible at
the moment because a lot of tests rely on zooming only iframes. Some of
them can be adjusted for scaling the top instead, but not sure it's
worth it's worth fixing them and moving the zoom to be top-only, as it'd
be a bunch of effort, and the complexity and overhead of propagating the
zoom is not so big.
The print-preview-specific code in nsContentViewer is from before we did
the document cloning setup, and it seems useless. I've tested print
preview scaling before and after my patch and both behave the same.
The rest is just various test changes to use the SpecialPowers APIs or
BrowsingContext as needed instead of directly poking at the content
viewer.
I named the pres context hook RecomputeBrowsingContextDependentData, as
more stuff should move there like overrideDPPX and other media emulation
shenanigans.
I also have some ideas to simplify or even remove ZoomChild and such,
but that's followup work.

Implemecurnt a flag `suspendMediaWhenInactive` on the docShell that indicates media in that shell should be suspended when the shell is inactive. Currently, only GeckoView is using this flag.
---
The reason of implementing this flag is because in bug1577890 we remove the old way to suspend/resume the media, and I thought setting docshell to inactive is enough to suspend the media because we already have a mechanism which would suspend/resume media when document becomes inactive/active [1].
However, the active state of document is actually different from what I thought it was. Setting docshell to inactive won't change the document's active state, because that indicates if the document is the current active document for the docshell [2] (docshell can have multiple documents), instead of indicating if the docshell is active or not.
Therefore, we have to add another flag to indicate if the docshell wants to suspend its media when it's inactive, in order to use current mechanism to suspend/resume media.
