qcacmn: Refactor Ramdump API and PKTLOG API

Ramdump collection can be supported by buses other than PCIe, and
it's done in offload layer when recovery is required. Hence allocate
memory dynamically and free it once ramdump collection is complete.

PKTLOG is a DataPath Feature, HIF doesn't need to have any info
of it. Move pktlog implementation to HTT folder.
