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.

The existing infrastructure which stored cached BrowsingContexts on the
BrowsingContextGroup was added before WindowContexts were added, and can cause
racing issues with partially discarded trees during process switches.

This was previously true, since we only used ResumeRedirectedLoad with a brand new docshell. This bug adds code for using it with existing docshells, which can have any Document (and associated timing object) loaded in them.

Same process origin changes are handled by the docshell, which detects this during AsyncOnChannelRedirect and clears the mixed content permission.
Process switches load in a fresh docshell, so we need to make sure we appropriately set or clear the mixed content permission.

This patch introduces a new tab modal system prompt type. It can be opened via the nsIPromptService
with a destination BrowsingContext. These tab system prompts overlap slightly with the upper
chrome UI to differentiate them from content prompts (previously called tab prompts).
- Extended nsIPromptService and nsIPrompt to accept 3 types of modal prompts:
- Window prompts
- Tab (system) prompts
- Content prompts (the old tab prompts)
- Removed prompt code from Prompter.jsm, always call PromptParent window actor instead
- Added PromptChild window actor to forward pagehide events to parent actor
- Created additional prompt methods in nsIPromptService to prompt by browsingContext and modalType
- Backwards compatibility is maintained, consumers can still open content prompts calling nsIPrompt with a content window

Currently, with Fission enabled we are not able to create a proper LoadInfo
object when doing a subdocument load because we do not have access to a loading
context if the load is happening inside of an OOP frame. To solve this problem,
we can create LoadInfo object from scratch in the parent process where we have
all of the required information.

This fixes the content policy type for document loads in these frames, where
the explicit mIsFrame flag was not set, due to DocShell creation taking a
different code path in remote frames than in in-process frames.

Add ParentProcessDocumentChannel object. This object is a DocumentChannel that will start a channel load from the parent process via a DocumentChannel.
The aim of this task is two-fold.
1- Be consistent on how we handle redirects before continuing the load on the final channel.
2- Prepare to initiate a process switch when needed without having to go via an intermediary content process, saving a process switch. This task will be done in a follow-up task.
The behaviour of the ParentProcessDocumentChannel is similar in logic to the DocumentChannelChild/DocumentChannelParent pair.
The ParentProcessDocumentChannel sets up a DocumentLoadListener, have it handle the redirects and upon completion continue the load on the final channel.
