Start simplifying FFI ownership sugar
This is step one of a series of changes planned to make the ownership sugar easier to use. This was blocked on #13038
*very* unsure about second commit. Don't like the thought of accepting types with destructors over FFI. Probably will revert it. Leaving it in for now in case you have some insight.
Eventually at least for the borrowed stuff I want to use T directly (because the crates are merged now), instead of the fake void types. Perhaps for the others too. I might include those changes in this PR -- was originally planning to but I realized that these steps could be split out.
Tentative plan for `Owned` (assuming it's not removed) is to have `Owned<T> <-> Box<T>` (same `T`, no "FFI type") conversions. We will only use ownership wrapper types for things with destructors, and try to keep the conversion simple. I'm envisioning a couple methods for arc/strong and a few more for box/owned. We may need to introduce new wrapper types for gecko-side managed objects (`RefPtr<T>`, `UniquePtr<T>`) but that should be all the wrapper types we have in the ownership sugar.
This PR relies on the guarantee that `Option<&T>` and `Option<Box<T>>` are pointer-sized via the `NonZero` optimization. I am now less unconvinced that this is a good idea 😉.

This adds support for more background-repeat modes using the legacy
rasterization backend.

Use conditional compilation for stylo properties; output unimplemented logs for all properties
Till now we were only emitting unimplemented property logs for properties which servo implements but stylo doesn't.
This list is getting smaller, and we really should be emitting this for any unexpected property we encounter.
I also made it so that longhands which stylo does not implement will not be compiled in stylo builds; instead of what we currently do,
which is to parse them and then basically ignore the result.
There are still a few exceptions -- we generate stubs for properties that are parts of shorthands because otherwise we'd have to add fiddly conditional compilation to the shorthand code.

We had code relying on `nsStyleCoord::set()` being leaky (like it was before we
patched up the calc bindings). Added `nsStyleCoord::null()` for this use case
since it's not possible to construct directly anymore.
