WebKit export from bug: [<!---->IFC]<!----> IFC cannot compute intrinsic widths when inline content has form controls

<pre>
[IFC] IFC cannot compute intrinsic widths when inline content has form controls

canUseForIntrinsicWidthComputation still sends form controls with native appearance and no fixed width, and controls like a
list box whose options have no renderers, to the legacy intrinsic width walk.

Their widths now come from the render tree like any other atomic inline-level box. A change that resizes a control (e.g. a
new select option) invalidates the container's content widths, which resets the cached intrinsic widths.
