Not headless by default
Without this, initializing Servo without using the command line (when embedded) requires to explicitly set `opts.headless = false`, which is weird as it's the only option that needs to be changed.

make gl context current on browser initialization
As explained in servo/webrender#1233, it's necessary to make the current gl context current when the browser is initialized, otherwise the wrong gl context might be used if another window is created before the initialization.

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.

style: Refactor the cascade function.
The `cascade_primary_or_pseudo` function was nice when we shared more code, but
right now I think it just makes it harder to understand what's going on.

Renamed constellation::Frame to constellation::BrowsingContext
<!-- Please describe your changes on the following line: -->
Now that script has `WindowProxy` rather than `BrowsingContext` objects, we can rename `Frame` in the constellation to `BrowsingContext`. In particular, this means that `FrameId`s are now `BrowsingContextid`s, which better captures their purpose (and they are used in a lot of places, not just the constellation).

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.
