Bug 1767172 - Remove custom screen info handling from GfxInfo, use ScreenManager for that. r=jrmuizel,handyman,stransky

This removes a bunch of custom code from GfxInfo to obtain screen
information, and instead collects that screen information in
ScreenManager.

This, apart of removing duplicated code, has the extra benefit of
reporting multi-monitor information on GTK (and potentially in the
future reporting scale and refresh rate properly as well, I've kept the
telemetry as it was on that regard).

Bug 1765399 - Invert the relationship between VsyncSource and VsyncDispatcher: The VsyncDispatcher now owns the source. r=smaug

This makes vsync source swapping much more natural.

The VsyncSource now only has a reference to the VsyncDispatcher for the duration
during which the dispatcher is listening to vsync. Whenever the dispatcher is
not listening to vsync, the source has no reference to the dispatcher and there
is no cycle.

This patch also adds the ability to register multiple dispatchers with the same
source. This ability is not used yet; a vsync source always has zero or one
dispatchers at the moment. It is in preparation for a future patch where there
will be one dispatcher per widget.

Furthermore, nothing uses gfxPlatform::GetGlobalVsync anymore, so it is removed.

This makes it so that the VsyncSource doesn't need to keep track of the compositor vsync dispatchers.

Once we have one VsyncDispatcher per window, we can probably eliminate CompositorVsyncDispatcher.

Every `VsyncSource` currently only has a single `Display` associated with it.
This means that we're not making use of the `Display` abstraction at all.
This patch gets rid of `Display` by merging it into `VsyncSource`.

Originally, the intention of the `Display` abstraction was to use it for
per-monitor vsync. There would be one software `VsyncSource` and one hardware
`VsyncSource`, and the hardware `VsyncSource` would have one `Display` per
screen. But in reality, things have played out differently: The only platform
with per-monitor vsync is currently Linux Wayland, which has per-**widget**
vsync. And it has chosen to have one `VsyncSource` per widget, with a single
`Display` each.

For the macOS implementation of per-monitor vsync, I think it also makes
sense to have one `VsyncSource` per screen.

We already need to handle switching between VsyncSources, for switching
between software and hardware vsync, if the pref `layout.frame_rate` is
changed. So we might as well reuse that same switching capability for
switching between screens, when a window moves between screens or when a
tab moves between windows on different screens.
