The existing code wasn't sound, as CSSOM objects also needed to go away before
the shared memory goes away (as they keep references to them).
This is sound assuming no presence of reference cycles introduced by CSSOM.
We may want to live with this and rely on chrome code not writing cycles like
this with UA stylesheet DOM objects.
We could explicitly drop all potentially-static objects... That seems pretty
error prone though.
Or we could also just leak the shared memory buffer, is there any reason why we
may not want to do that?

For developing properties, we will handle them in an other bug.
Besides, I use an iframe for the test because we create a use counter in
the constructor of Document, which use the prefs to decide what kind of
properties we want to record. So, in the test, we have to reload iframe
to make sure we re-create the document, so does the use counter, to make
sure the prefs work properly.
The two prefs affect the css use counters:
1. layout.css.use-counters.enabled: Allocate use counters, and record
non-custom properties.
2. layout.css.use-counters-unimplemented.enabled: Record all unimplmented
properties into the use counters.
If we disable layout.css.use-counters.enblaed, we don't create use counters
object, so layout.css.use-counters-unimplemented.enabled doesn't work,
either.

I'm _really_ sorry for the size of the patch. I tried to do this in two steps
but it was a lot of work and pretty ugly.
This patch makes us use cbindgen for grid-template-{rows,columns}, in order to:
* Make us preserve repeat() at computed-value time. This is per spec since
interpolation needs to know about repeat(). Except for subgrid, which did the
repeat expansion at parse-time and was a bit more annoying (plus it doesn't
really animate yet so we don't need it to comply with the spec).
* Tweaks the WPT tests for interpolation to adopt the resolution at:
https://github.com/w3c/csswg-drafts/issues/3503.
Trade-off here, as this patch stands, is that this change makes us use less
long-living memory, since we expand repeat() during layout, but at the cost of a
bit of CPU time during layout (conditional on the property applying though,
which wasn't the case before). It should be very easy to store a cached version
of the template, should this be too hot (I expect it isn't), or to change the
representation in other ways to optimize grid layout code if it's worth it.
Another trade-off: I've used SmallPointerArray to handle line-name merging,
pointing to the individual arrays in the style data, rather than actually
heap-allocating the merged lists. This would also be pretty easy to change
should we measure and see that it's not worth it.
This patch also opens the gate to potentially improving memory usage in some
other ways, by reference-counting line-name lists for example, though I don't
have data that suggests it is worth it.
In general, this patch makes much easier to tweak the internal representation of
the grid style data structures. Overall, I think it's a win, the amount of magic
going on in that mako code was a bit huge; it took a bit to wrap my head around
it.
This patch comments out the style struct size assertions. They will be
uncommented in a follow-up patch which contains some improvements for this type,
which are worth getting reviewed separately.
Also, this patch doesn't remove as much code as I would've hoped for because of
I tried not to change most of the dom/grid code for inspector, but I think a
fair bit of the nsGridContainerFrame.cpp code that collects information for it
can be simplified / de-copy-pasted to some extent. But that was a pre-existing
problem and this patch is already quite massive.
