Attachment: Bug 1726708 - Add stable key for spatial nodes

Add an interface (and update Gecko to provide) a stable unique
identifier for each spatial node that is consistent across
display lists.

Although this patch doesn't do anything useful with this yet,
we'll use this in future to allow interning, persisting and caching
a lot more information related to primitives and clips.

For now, it just asserts that the calling code never supplies a
duplicate unique identifier - which will be useful to have running
in nightly for a couple of weeks before starting to make use of
these identifiers.
