crypto: qat - add compression slice count for rate limiting 



In QAT GEN4 devices, the compression slice count was tracked using the
dcpr_cnt field.

Introduce a new cpr_cnt field in the rate limiting (RL) infrastructure to
track the compression (CPR) slice count independently. The cpr_cnt value is
populated via the RL_INIT admin message.

The existing dcpr_cnt field will now be used exclusively to cache the
decompression slice count, ensuring a clear separation between compression
and decompression tracking.
