Fix a missing GN dependency from web_applications/extensions to //chrome/common

Add a missing dependency from web_applications/extensions to //chrome/common,
as BookmarkAppDataRetriever uses chrome::mojom::ChromeRenderFrame.
This should fix a flaky build error on bots:

../..\chrome/browser/web_applications/extensions/bookmark_app_data_retriever.h(12,10):  fatal error: 'chrome/common/chrome_render_frame.mojom.h' file not found
#include "chrome/common/chrome_render_frame.mojom.h"
