Bug 1544343 - part 2: Make factory methods take mozilla::PresShell instead of nsIPresShell r=emilio

Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead.  So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).

Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.
