Make hung renderer dialog group with browsers on Windows.

The hung renderer dialog did not explicitly set its app id. This causes
unpredictable grouping. This patch explicitly sets the app id of the
hung renderer dialog to the app id of browsers of the same profile.

BUG=306961
TEST=With chrome exited, open app launcher. Open a chrome tab which points at google.com. Enter chrome:hang into the url bar. The dialog that pops up after a few seconds should be grouped with the browser and not the app launcher.
