Add user status on user profile icon (#33653)

* Add user status on user profile icon

Currently unstyled & no tests

* Style the user status icon

* Update snapshot

for avatar wrapper

* More snapshot updates

* add if braces

* Split out user status functions

to avoid circular dep which has the weird effect of just breaking
jest's mocking.

* type imports

* Update imports

* Update snapshot

* Tests

* baseline image

* Just snapshot the component itself
