The API is currently not working. It is mostly about implementing the shell: it
exposes document.pictureInPictureEnabled, document.exitPictureInPicture(), and
video.requestPictureInPicture(). It also adds the "picture-in-picture" feature
policy. Everything is gated by the "PictureInPictureAPI" runtime feature.

A misread of the spec made us skip out-of-flow boxes merging anonymous
flex items. Only merge anonymous flex items which are truly box
siblings.

Adjusted the wpt tests accordingly. Fwiw, Firefox nightly now passes
all of wpt/css/css-flexbox/anonymous-*

This change renames public/interfaces to public/mojom and *_struct_traits_*
to *_mojom_traits_* in //device.

As a side effect the //device/vr/public/mojom directory was created to hold
vr_service.mojom and //device/screen_orientation/public/interfaces was moved
to //services/device/public/interfaces as the rest of that directory had
already been moved to //services/device.

This patch implements the new CSSMathValue serialization algorithm [1].
As explained in the bug, this serialization is impossible to do by
converting to CSSValues and then serializing them, so we have to
implement this from scratch.

We tried to make the code follow the spec algorithm as closely as
possible for easier understanding/verification.

According to the shortest-serialization principle [1], values should be
omitted if their omission wouldn't change the value of reparsing. As
"1"/"on" is the default value for font-feature-settings, omit this when
serializing, matching the behavior of Firefox.

The current spec says that it isn't nullable [1]. This CL also removes
null check in client-navigate-worker.js. There is test coverage for null
clientId in fetch-event.https.html so the explicit check here is not
needed.

You can find spec discussion in [2].

Fixes web-platform-tests#3374.

We had been using the same checks for both object and any Web IDL types to
determine if they were present, namely

    !(member.IsEmpty() || member.IsNull() || member.IsUndefined())

However, both `null' and `undefined' are valid values for the any type, and
they should be considered distinct.

Add a separate check for any types without the "member.IsNull()" part of the
above one, so that one can pass `null' to an any member and get it back
instead of `undefined'.
