Fix containing block size for absolute root element
The root element doesn't have a containing block, so use the viewport size instead of `self.base.absolute_cb`.

Implement Houdini worklets
<!-- Please describe your changes on the following line: -->
This PR implements the current draft Houdini Worklets specification (https://drafts.css-houdini.org/worklets/).
The implementation is intended to provide a responsive environment for worklet execution, and in particular to ensure that the primary worklet executor does not garbage collect, and does not block loading module code. The implementation does this by providing a thread pool, and performing GC and module loading in a backup thread, not in the primary thread.

Don't optimize display list for projective transforms
There are situations where elements are transformed from outside the
display list. With projective transforms it's currently difficult to
detect these. In those cases we just don't optimize the display list,
so that they will always be shown.
Fixes#13822.

Root nodes for the duration of their CSS transitions
This ensures that we can pass a node address as part of the asynchronous
transition end notification, making it safe to fire the corresponding
DOM event on the node from the script thread. Without explicitly rooting
this node when the transition starts, we risk the node being GCed before
the transition is complete.

Make cross-origin canvas drawing tests use a same-origin redirect.
These tests either pass or maintain existing known failures in Firefox and Chrome, and expose the problem in our current implementation that #15887 is addressing.

In a similar way to Position, now specified and computed gradients share
a common Gradient type defined in style::values::generics::image.
This allows us to reuse most code for many style traits like ToCss,
HasViewportPercentage and ToComputedValue.
The test changes are the fallout of the disappearance of AngleOrCorner::None,
which align our code to the spec for serialisation, where components that can
be omitted should be omitted.
This patch implements the following changes:
- Only check for the toplevel/sublevel part of the mime type when
deciding if it's a js or css resource, ignoring the mime parameters.
- Fix the wpt tests that did not escape url parameters properly and
also used an invalid syntax for the mime parameter.
- Update the wpt manifest.
We need another flag that represents allow-negative-number for SMIL, so
this enum will also comprise the another parsing mode that allows negative number.
Disallow negative duration for animation and transition
