[AF][Status Chip] Move save card icon into toolbar status chip

1) Change is similar to the one moving LocalCardMigrationIconView into
the status chip.

2) In the browsertes I used card local save flow to verify.
Didn't add more browsertests since all bubbles update icon through
the same UpdateIcon() function, if one bubble works fine then all
types of bubbles and their related save card icon should work fine.

3) Uploaded implementation screenshot in bug comment#3
