BubbleFrameView: Replaced GetCloseButtonBounds with
GetCloseButtonMirroredBounds. Now returns the RTL-mirrored bounds, which
is necessary for the App Info dialog's FullSizeBubbleFrameView to
correctly target events to the close button in RTL mode.

BUG=474559
TEST=Change language to Arabic. Go to chrome://extensions; click
"Details" on any extension. Click X button. Should close dialog.
