Log UserDeletedCookieOrCacheFromDialog from Android

We currently log the UserDeletedCookieOrCacheFromDialog histogram from
Desktop. On Android we only know about total cookie/cache deletion
and not those started from CBD.
This CL adds logging of the UserDeletedCookieOrCacheFromDialog histogram
to the CBD dialog on Android.
