### Story
While the exisiting top browsing context is replaced, SessionStorage relies on
itself been propagated by SessionStore. However, this has been disabled in
SessionHistory in the parent process.
Therefore, we need to propagate SessionStorage data by propagating
BackgroundSessionStorageManager.
### Notes
This patch assumes that the target top-level browsing context shouldn't have
been registered to BackgroundSessionStorageManager. If this can happen, we will
either need to merge SessionStorage data into it or find a proper (earlier)
place to update sManagers.

To allow `requestAnimationFrame()` and similar things to run at monitor
speed if there is only a window-specific vsyncsource available.
This is the case for Wayland and, in the future, EGL/X11. Other backends
may opt for window specific vsyncsources as well at some point.
The idea is to, instead of using global vsync objects, expose a vsyncsource
from nsWindow and use it for refresh drivers. For the content process, move
VsyncChild to BrowserChild, so for each Browserchild there is only one
VsyncChild to which all refresh drivers connect.
IPC in managed either by PBrowser or PBackground. Right now, PBrowser is
only used on Wayland, as both PBrowser and the Wayland vsyncsource run
on the main thread. Other backends keep using the background thread for
now.
While at it, make it so that we constantly update the refresh rate. This
is necessary for Wayland, but also on other platforms variable refresh rates
are increasingly common. Do that by transimitting the vsync rate `SendNotify()`.
How to test:
- run the Wayland backend
- enable `widget.wayland_vsync.enabled`
- optionally: disable `privacy.reduceTimerPrecision`
- run `vsynctester.com` or `testufo.com`
Expected results:
Instead of fixed 60Hz, things should update at monitor refresh rate -
e.g. 144Hz

The new infrastructure consists of a separate bridge between the content and the
parent process and a separate local storage database in the parent process.
The new infrastructure can be used for storing and sharing of private browsing
data across content processes.
This patch only creates necessary infrastructure, actual enabling of storing and
sharing of data across content processes will be done in a follow-up patch.

And we remove unnecessary checks, BackgroundParent only run in the parent process and if e10s is on. Also RecvLauchRDDProcess will only ever be called if the rdd pref is on already.
By streamlining the call we also reduce the number of sync dispatch to 1.

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).

Each existing GamepadTestChannel needs to know when gamepad monitoring is
started or stopped so it knows whether it's safe to deliver messages.

Change the GamepadEventChannel so it is fully-initialized by the IPC
constuctor and needs no separate "init" message, and so its completely
destroyed by the ActorDestroy() message so it needs no "cleanup" message.
This simplifies the object lifetime, as well as unifies the IPC error vs
clean shutdown paths.
