wifi: ath11k: Register DBR event handler for CFR data

Browse source 
Add handler for WMI_PDEV_DMA_RING_BUF_RELEASE_EVENT which indicates CFR
data availability in the DB ring.

Add CFR data processing from DB ring buffers. Use correlate_and_relay
API to match CFR data with metadata from WMI_PEER_CFR_CAPTURE_EVENT.

Release buffer to userspace through relayfs on successful correlation,
otherwise hold buffer waiting for matching WMI event from firmware.

Add new debug masks:
 - ATH11K_DBG_CFR:      Enables CFR-related debug logs.
 - ATH11K_DBG_CFR_DUMP: Enables detailed CFR data dump for analysis.
