By resolving the relevant promises, instead of crashing (and if we
didn't crash we'd leave the window registered as a refresh driver
observer, which would be bad).
I wanted to reject them, since that's what we do when the page has no
pres shell, but that'd make this test fail:

For this, we modify the OneShotPostRefreshObserver API to be more
generic (and rename it OneShotManagedRefreshObserver).
We fix APZ's usage of this API, which was doing something extremely
weird (returning a refcounted object in a UniquePtr). This seems like an
artifact from recent OneShotPostRefreshObserver cleanup.

When a contentful paint occurs which doesn't come from Tick, we should
not generate a first-contentful-paint entry for it because
1) It violates the spec
2) It usually means some magical paints which we should not expose
to the web.
So this patches stop generating a contentful paint entry for that,
instead asking the next tick to generate the entry.

OneShotPostRefreshObserver works as the caller registers it, and
let it deletes itself via the DidRefresh method. The issue is that
DidRefresh is not guaranteed to run, and it'll leak PresShell
if it doesn't run.
This patch allows nsPresContext to store and release the last
registered OneShotPostRefreshObserver, and converted the existing
usage of OneShotPostRefreshObserver to use that. So instead of asking
OneShotPostRefreshObserver to delete itself, we now ask nsPresContext
to release it.

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

This creates a marker that starts when an observer is added and ends when it is removed.
If there are multiple observers at the same time, their markers overlap.
The current profiler markers API only lets us insert the marker once we know
both the start and the end timestamp. This means that, if a profile is captured
in the middle of a refresh observer's observation period, there will not be a
marker for that observer in the profile. This can be improved once we have a way
to emit separate start and end markers and a way to associate the correct markers
with each other (bug 1661114).

The name `AUTO_PROFILER_MARKER_TEXT` is more consistent with the equivalent non-`AUTO` macro, and similarly arguments have been re-ordered to be the same, i.e.: Name, category&options, text.
The different macros with different argument sets can now be collapsed into one macro, and the optional arguments (timing, inner window id, backtrace) can easily be added to the `MarkerOptions` where needed.
As a bonus, a specific start time can optionally be provided at construction time.
