The SpecialPowers set*Pref/get*Pref APIs currently use synchronous messaging
to set and get preference values from the parent process. Aside from directly
affecting callers of those APIs, it also affects callers of `pushPrefEnv`,
which is meant to be asynchronous, but is in practice usually synchronous due
to the synchronous messaging it uses.
This patch updates the getPref APIs to use the in-process preference service
(which most callers are expecting anyway), and also updates the callers of
the setPref and pushPrefEnv APIs to await the result if they're relying on it
taking effect immediately.
Unfortunately, there are some corner cases in tests that appear to only work
because of the quirks of the current sync messaging approach. The synchronous
setPref APIs, for instance, trigger preference changes in the parent
instantly, but don't update the values in the child until we've returned to
the event loop and had a chance to process the notifications from the parent.
The differnce in timing leads some tests to fail in strange ways, which this
patch works around by just adding timeouts.
There should be follow-ups for test owners to fix the flakiness.

When we migrate SpecialPowers to a JSWindowActor, it will no longer be able to
use synchronous IPC messaging, which means that its current synchronous APIs
will have to become asynchronous.
This patch doesn't change the behavior of those functions, but it does change
their callers to `await` their return values rather than using them directly.
This pattern will work the same whether the functions return a promise or a
plain value, which simplifies the migration.

for the case srdoc iframe. We should use the last non-srdoc parent

gfxPlatform::GetSourceSurfaceForSurface and CreateDrawTargetForSurface
are both static methods that we sometimes use via the pattern
gfxPlatform::GetPlatform()->... This is problematic because this forces
gfxPlatform to be initialized in the process, and in the GPU process, we
don't support this. It should be safe to call these methods without
initializing gfxPlatform, so this patch removes the GetPlatform() call.
GetSourceSurfaceForSurface may end up initializing gfxPlatform anyways,
depending on whether or not a DrawTarget was given. This should not be a
concern for the crashes observed in bug 1435586.

this adds extra guards to make sure we don't allow them on 308s
