This is a test-only change. It introduces a new Urlbar pref to make the
existing 3000 ms timeout configurable.

That timeout is currently reached 8 times in the test. That means that
the test will take at least 3 x 8 = 24 seconds to run while basically
doing nothing, and makes the test prone to reach the deadline by which
the test is declared timed-out.

To avoid "Test timed out" errors, the test now reduces the fixed 3000 ms
timeout to 500 ms, so now we wait for 8x500 = 4 seconds instead of 24.

Differential Revision: https://phabricator.services.mozilla.com/D170024

This change computes the new invalid region of the in progress surface
during the partial update, and asserts that the update region is
sufficient to cover it. This will assert earlier than the asserts in
NotifySurfaceReady, under similar conditions. Hopefully this will help us
identify if we are using an incorrectly calculated update area.

Additionally, it reorganizes the region boolean logic in
NativeLayerCA::HandlePartialUpdate to avoid adding in the update region
just to subtract it away again.

It also confirms that callers to the layer are always either using the
drawn surface call (NotifySurfaceReady) or the external surface call
(AttachExternalImage).

Bug 1747585: Stop forcing specialized video layers due to DRM, when the OS doesn't respect DRM. r=mac-reviewers,mstange

Forcing specialized video in this case was overriding the user's ability
to opt-out by setting the pref, while providing no benefit. Adding the
macOS version check around this makes our logic here consistent with our
setting of preventsCapture in ApplyChanges.

The issue in the bug is that we were returning a `DebugEnvironmentProxy` to JS
through `findPath`/`UbiNode`, and this object isn't safe to use from arbitrary JS.

This patch also changes `findPath` to not define the `node` property with `--fuzzing-safe`,
to fix similar issues elsewhere. This `DebugEnvironmentProxy` case is easy to fix, but
the engine also uses plain objects and arrays internally in some places and the `JSClass`
checks won't be sufficient for that.
