[Mac][MD User Menu] Fixed the accessibility string of profile button

The new profile card button needs an accessibility string since it has
no label. The string would be "Edit person, <profile name>" or "Edit
person, <profile name>, <email>" for signed in profiles. See first bug.

Tested with VoiceOver.
