Persona is a Frappe app that Allows Administrator or a system manager to impersonate another user. Inspired by Administrator should be able to impersonate any user #17615.

1. Only "Administrator" or "System Manager" roles can impersonate another user.
2. Adds a button "Impersonate" to User form.
3. Will generate 2 entries in activity log.
   1. One will show that the Administrator/System Manager who is impersonating a user.
   2. A second entry shows that the impersonated user logging in.
4. As a safeguard, we don't allow a system manager to impersonate another system manager.
