Share and copy menu items for account page (#3120)

* Share and copy menu items for account page (first attempt)]

* Always include domain in username in 'handle' copy

* Remove profile copy options, rename 'handle' to 'username'

* Long press on username in profile to copy it to clipboard

* Changes for code review: localUsername not username, Snackbar not Toast

* Do not trust getDomain() when getting full username. This means full-username build has to happen in AccountActivity instead of Account

* Replace != null -> \!\! idiom with more kotlin-y (and more threadsafe) ?.let pattern

* Unnecessary import

* Comment clarifying safety of \!\!
