Aside from automating boilerplate, this will allow reusing some of these
structs for full LookAndFeel remoting in bug 1470983.

In bug 1595994 we attempted to streamline the ability to determine which decoder was available regardless of the process they would be running in. This was subsequently done via the PDMFactory.
As there are several JS API that can query which codec are supported, it requires a synchronous mechanism.
This allowed to make a determination during the PlatformDecoderModule::Supports call, depending on which process it was going to be called frome.
Having a synchronous IPC call to the RemoteDecoderManagerParent has too many caveats to be workable.
So what we do instead is first determine at launch if the required external framework are available and pass this information to each content process.
When checking if a decoder is available, we make a best guess at determining if the PDM would support such codec, without actually loading such framework when running in the content process.
Supports can no longer make a decision based on the process currently running and as such PDM::CreateAudio/VideoDecoder using an optional system framework now need to further check the validity of the CreateDecoderParam argument.

This should make the optimization landed earlier in this bug apply for
some of the NotifyThemeChanged() calls in nsWindow.cpp which are causing
all the extra invalidations.
If we know that system colors/fonts didn't change, we can avoid doing a
bunch of reflow work and the patch from earlier in the bug can avoid
re-rasterizing images too.

This patch does:
- Use LSWriteOptimizer
- Remove SessionStorageService since it's unused.
- Move IPC from PContent to PBackground
(by SessionStorageManager{Child, Parent} and SessionStorageCache{Child, Parent}).
- Extract SessionStorageManagerBase and add PBackgroundSessionStorageManager.
- Expose a getter function to get a BackgroundParentManager for top context id
on the parent.
IPC
- Before this patch:
- Copy from parent while loading a document.
- Mark cache entry on the parent process as loaded by the child id.
- Update change on checkpoint.
- Unmark cache entry on the parent process as unloaded for the child id while
the parent actor is destorying.
- After this patch:
- Sync IPC load in the first SessionStorage operation.
- Update change on checkpoint
`BackgroundSessionStorageManager`'s lifecycle on the parent process.
- Create by `SessionStorageManagerParent` and register to the `sManagers`.
- Hold by `SessionStorageManagerParent` and `sManagers`.
- Remove from the `sManagers` while the corresponding `BrowsingContext` is
destructed (on the parent process).

In order to avoid over/under-counting, we need to treat window.print()
specially. The new UI was using aOpenWindowInfo.isForPrintPreview for
that, but that doesn't quite work for the old UI (because it will
trigger a regular print, not a preview).
But since isForPrintPreview was only really needed to distinguish
window.print(), just rename it and set it to true when the old UI is
triggered by window.print() as well.

This works, though probably we want to do some follow-up tweaks, like
the adding of the onload blocker and so on, so that we can avoid the
UpdateDimensions hack.
We may also want a PrintObject in the nsPrintJob tree, perhaps...

This has couple of different pieces and one may want to focus on each of those separately when
reviewing. The first two as small changes.
- Moving mDynamicallyCreated from nsDocShell to be a sync'ed field on BrowsingContext.
CanonicalBrowsingContext::CreateLoadingSessionHistoryEntryForLoad sets that on a newly created entry.
- Adding mActiveEntryIsLoadingFromSessionHistory. mLoadingEntry + mActiveEntryIsLoadingFromSessionHistory has roughly
the same lifetime as mLSHE. mLoadingActiveEntry is needed so that child docshell can know whether its parent is loading from session history.
- The main part is in MaybeHandleSubframeHistory which checks if the parent docshell is loading from session history,
and if so, asks for a LoadingSessionHistoryInfo. In the case of docshell living in a child process that operation is asynchronous,
so when the data is back from the parent process, LoadURI is called again with the possibly updated data.
One could possibly split the code to smaller methods and then deal with aContinueHandlingSubframeHistory only in LoadURI,
but MaybeHandleSubframeHistory does have some early returns which would make that approach possibly hard to follow.

This backs out all work from bug 1627075 as well as all of its
descendents. There were a few conflicts when backing this out but
overall it was pretty clean, so I would say it's a fairly mild
level of risk. Historically Nathan Froyd has reviewed these patches,
but he is no longer at Mozilla, and no one else is particularly
familiar with the code, so I am passing this off to RyanVM who has
at least been familiar with the history of the bug.
