REGRESSION (272448.703@safari-7618-branch): [iOS] <input type=file> c…

…amera capture instantly dismisses

rdar://125046135

Reviewed by Abrar Rahman Protyasha and Wenson Hsieh.

272448.703@safari-7618-branch added logic to dismiss presented pickers, such as
the file upload panel, when the `WKWebView` was removed from the hierarchy. The
behavior is necessary to avoid scenarios where a picker can be displayed over a
site that's unrelated to the one requesting the information.

While that solution is correct for modal presentations, it is incorrect for
fullscreen presentations, which remove views from the hierarchy following
presentation. The camera view controller uses a fullscreen presentation.
Consequently, once it gets presented, the web view is removed from the
hierarchy, and following 272448.703@safari-7618-branch, it is instantly
dismissed.

To fix, reduce the scope of the previous fix to exclude fullscreen presentations.
In this case, there is no need to dismiss presented view controllers, as the
web view content is already hidden.

Note that there is no way to detect whether a view was removed from the hierarchy
due to a fullscreen presentation. Consequently, the solution checks the status
of various presented pickers.

* Source/WebKit/UIProcess/Cocoa/PickerDismissalReason.h:

Introduce `PickerDismissalReason`s to control the dimissal behavior.

In particular, `ViewRemoved` now checks for fullscreen presentations, to avoid
instant dismissal.

`ProcessExited` is used here, since it has the desired semantics.

In effect, the remote process of the host view controller is exited here.
