When intenting to the select-webview-implementation Dev Setting a user won't know which package is currently being used as WebView implementation. To solve this we change the background color of the item representing the current WebView package. With this CL, also ensure we update the summary of the WebView implementation Dev Setting even if we failed to switch to the package chosen by the user - we might have switched to another package instead. Bug: 34702900 Test: Ensure the current WebView package has a different background color than the rest of the packages. Change-Id: Ieb65fdc635d5dd1253931c8ab8bb0d827a142c56
