Promote AVCTP version to 1.4

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.
