Rename ShowChromeAppInfoDialog to ShowAppInfoDialog

Rename ShowChromeAppInfoDialog to just ShowAppInfoDialog, which is a more
correct name for the app info dialog. The reason this was originally called
ShowChromeAppInfoDialog was because the name was based on
ShowChromeAppCreateShortcutsDialog, which was named that way to distinguish it
from ShowURLAppCreateShortcutsDialog.
