qcacmn: Add support for fragmented history recording

Currently the history recording for any debug purpose
is done using a contiguous memory chunk. For certain
history like tx_hw_ring, tx desc or tx completion desc
history, the amount of contiguous memory required is
very huge (order 7 or 8 allocation), which have a
higher probability of failing.

In order to mitigate the above scenario, introduce the
support for recording debug history into fragmented
chunks of memory, thereby reducing the requirement of
contiguous memory.
