wifi: ath12k: Use 1KB Cache Flush Command for QoS TID Descriptors

Currently, if the descriptor size exceeds 128 bytes, the total
descriptor is split into multiple 128-byte segments, each
requiring a separate flush cache queue command. This results in
multiple commands being issued to flush a single TID, which
negatively impacts performance. To optimize this, use the
_FLUSH_QUEUE_1K_DESC REO command to flush a 1KB descriptor in a single
operation to optimize performance.
