[PW_SID:1037077] Enhanced or Legacy Accept Synchronous Connection Request command

[BluezTestBot]

In current implementaion kernel is sending legacy sco command
['Accept Synchronous Connection Request command'] always even
though controller supports enhanced synchronous connection
command.

In this commit, we have implemented the code in such a way that
when Connect request for eSco is received, if controller supports
enhanced synchronous connection command then it will go for
'Enhanced Accept Synchronous Connection Request command' or else
it will go for legacy command['Accept Synchronous Connection
Request command'].
