[Viewport Segments] Per CSS WG resolution move the JavaScript segment…

… property from window.visualViewport to the newly added window.viewport. See w3c/csswg-drafts#9237 (comment) for the full IRC log of the conversation. w3c/csswg-drafts#10564 is the PR adding the segments property part of the CSS Viewport Level 1 specification. There is no functional changes in how the segments property works, tests are updated to reflect the new position. Right now the viewport object is tied to the runtime flag of Viewport Segments because we expect the feature to ship before the viewport attribute receive more fields.
