Introduce a new QCA vendor command for host driver TX/RX counters

Add new vendor TX/RX counters to retrieve host/driver side specific
counters and drop counts.

Standard interfaces (e.g., station dump) typically reports aggregated
HW+SW statistics. This interface exposes separate host-side counters
to allow userspace to obtain host-level specific data, distinguished
from firmware/hardware statistics.
