qcacmn: qdf: Introduce QDF_FULL_MAC_FMT and QDF_FULL_MAC_REF

The idea behind introducing these macros is, if the feature
CONFIG_WLAN_TRACE_HIDE_MAC_ADDRESS is enabled, then the
requirement is to hide 2nd, 3rd and 4th octet of the
MAC address in the kernel logs and driver logs.
But other management interfaces like ioctl, debugfs, sysfs,
wext, unit test code or non-production simulator sw (iot_sim)
should continue to log the full mac address.

If the developer directly introduces %pM in the code, it becomes
difficult to catch this in the code review and may end up breaking
the feature CONFIG_WLAN_TRACE_HIDE_MAC_ADDRESS if enabled.

Hence the plan is to introduce meaningful macros to help code
audit easy and with the help of automation, block the developer
from directly introducing %pM in the code.
