xshu 5899e8e9a1 move ringbuffer interactions to wifi hal
Shallow copy of ringbuffer is stored inside the hal.
The maximum ringbuffer size is configured by the
framework.

overrides IBase::debug to:
1. write ringbuffers in memory to flash (wifi tombstones)
2. write wifi tombstones to lshal debug fd in archived format

Bug: 70171481
Test: compile, run on device
Test: run "lshal debug android.hardware.wifi@1.2::IWifi >>
archive.cpio" and compared archived files with originals using diff command
