This reverts commit 6d514087.

Reason for revert: b/149569123

Original change's description:
> [Chromecast] Refactor and Simplify CastWebView
> 
> CastWebView forces too much indirection from the underlying page/window
> functionality, so some forwarding methods have been removed in favor of
> calling the members directly. This is presently not ideal, but will be a
> great improvement once the CastWebContents and CastContentWindow are
> surfaced as mojo interfaces via CastWebService and their lifetimes can
> be tracked independently.
> 
> The CastWebService API has been simplified so that clients no longer
> need to provide a SiteInstance when creating CastWebViews. The renderer
> preloading logic, which was previously disjoint from CastWebView, has
> now been incorporated.
> 
> Merge-With: eureka-internal/331288
> 
> Bug: internal 77879457
> Test: CQ, manually verify on display assistant device.
