Promote AVCTP version to 1.4

Promoting AVCTP version to 1.4 from 1.2 as Bluedroid stack
already has got support for the same.
Below changes are incorporated as part of this:
 - AVCTP version in SDP entry is upgraded to 1.4 for both AVRCP
   Target and controller role.
 - Service class #1 is added in extra for AVRCP Controller SDP
   entry to be in sync with AVCTP version change.
 - Browsing support is not enabled as that needs corresponding
   profile level implementation, which is currently unavailable.
