Bluetooth: Shell: Add second vendor service

Browse source 
This adds a second vendor service testing if service changed indications
works with more than one change in a row and as a bonus it implements
echo attribute which notifies any data that is written to it:

> ACL Data TX: Handle 3585 flags 0x00 dlen 9
      ATT: Write Command (0x52) len 4
        Handle: 0x0013
          Data: 0000
< ACL Data RX: Handle 3585 flags 0x02 dlen 9
      ATT: Handle Value Notification (0x1b) len 4
        Handle: 0x0013
          Data: 0000
