Merge 121354 - Fix broken resize box appearance after download shelf open/close.

The issue was that currently only a WasResized() message updates the resize corner information in WebKit, but if the download shelf opens, the web contents don't necessarily get resized.

As a fix, add an IPC to explicitly update the resize rect, and call this when the download shelf opens/closes, and when a TabContents object becomes active.

Depends on https://bugs.webkit.org/show_bug.cgi?id=77453

BUG=111266
TEST=open page with scrollbar, save it. no resize corner in web.
switch to background tab with scrollbar, no resize corner there
either.
close download shelf, resize corner doesn't overlap scrollbar.
back to first tab, there neither.
