Bug 1585070 - move nsPIDOMWindowOuter::mIsActive to BrowsingContext. r=kmag

Browse Source 
A new `BrowsingContext` field has been added to track the active
browser window for the `:-moz-window-inactive` pseudoclass. This
field takes the place of `nsPIDOMWindowOuter::mIsActive`.

With this change `:-moz-window-inactive` is now fission compatible.
