Almost all the types in `values/specified` and `values/computed` share their `ToCss` implementations. The only reason they have duplicated code hanging around is a result of different specified and computed forms for types like `LengthOrPercentage`. This PR makes some of these types *generic* so that we could have a common definition and `ToCss` impl (`Parse` and `ToComputedValue` impls too, if possible).

-moz-transform property is an alias shorthand property. It has transform as sub-property but their parsing is different in some cases(matrix/matrix3d). -moz-transform also accepts LengthOrPercentage in the nondiagonal homogeneous components of matrix and matrix3d.
It looks like length and percentage values are getting computed to number directly. For example 120px converts into 120 and calc(120px + 20%) converts into 140. So I did like this. But we need to check this behavior again to be sure, I guess.
Also I spent half day investigating why matrices are not serializing after this change and found out their ToCss functions is not completely implemented yet 😄 I was going to implement them but there is an easy issue about it(#15194) so I left it that way. Probably all tests won't pass without it.

Instead of passing down a complex clipping region to each item, used
shared clipping to handle overflow:hidden and CSS clips. In addition to
being more efficient, this should also fix quite a few issues related
to absolutely positioned elements.
One existing reftest is slightly modified to avoid tickling a quirk
with the way that WebRender rasterizes masks. We are working out how to
best express these combined masks with the API or need to. The change
does not affect the original subject of the reftest.

When dealing absolutely positioned items, we should use clip of our

a new overflow clip. Additionally, we need to properly handle

This is the first step toward removing inherited clips in favor of
scroll roots for handling overflow and CSS clipping. This will allow us
to more easily handle elements that should not be clipped. While we are

Before this PR, every object reflected in CSSOM is in `Arc<RwLock<_>>` to enable safe (synchronized) mutable aliasing. Acquiring all these locks has significant cost during selector matching:
* https://bugzilla.mozilla.org/show_bug.cgi?id=1311469
* https://bugzilla.mozilla.org/show_bug.cgi?id=1335941
* https://bugzilla.mozilla.org/show_bug.cgi?id=1339703
This PR introduce a mechanism to protect many objects with the same `RwLock` that only needs to be acquired once.
In Stylo, there is one such lock per process (in a `lazy_static`), used for everything.
I non-Stylo Servo, I originally intended to have one such lock per document (for author-origin stylesheets, and one per process for user-agent and user sytlesheets since they’re shared across documents, and never mutated anyway). However I failed to have the same document-specific (or pipeline-specific) `Arc` reachable from both `Document` nodes and `LayoutThread`. Recursively following callers lead me to include this `Arc` in `UnprivilegedPipelineContent`, but that needs to be serializable. So there is a second process-wide lock.
This was previously #15998, closed accidentally.
