qcacmn: Add support to collect pktlogs as part of bugreport

浏览代码 
Add infrastructure in pktlog utils to collect pktlogs as part
of bug report generation. As part of this when pktlog read command
is received on host:
1. disable pktlog,
2. read pktlog,
3. clear pktlog buffer,and
4. Retain pktlog initial state
