SimPin for Flexiglass

Adds the sim pin screen for bouncer in flexiglass. One oustanding issue
is that when we authenticate with the authentication method None, we get
a black screen.

Fixes: 291970178
Flag: NONE
Test: test multiple sim cards unlock when restart device
Test: unlock one puk locked and one pin locked
Test: disable esim
Test: dialog messages
