automated: wlan-smoke: add new test

WLAN smoke test. This initial set of tests only verify the state of the
WLAN $DEVICE at boot (on or off) and test if the $DEVICE can be enabled and
disabled.

There is no WLAN transmission/connection.

== Example of test execution with test-runner on DB410c, running OE RPB:

name,test_case_id,result,measurement,units,test_params
wlan-smoke,ip-link,pass,,,DEVICE=wlan0;BOOT=enabled
wlan-smoke,wlan-boot,pass,,,DEVICE=wlan0;BOOT=enabled
wlan-smoke,wlan-down,pass,,,DEVICE=wlan0;BOOT=enabled
wlan-smoke,wlan-up,pass,,,DEVICE=wlan0;BOOT=enabled

== Static code analysis

$ python3 validate.py  -s SC1091 -g
* SHELLCHECK: [PASSED]: automated/linux/wlan-smoke/wlan-smoke-test.sh
* YAMLVALID: [PASSED]: automated/linux/wlan-smoke/wlan-smoke.yaml
* METADATA [PASSED]: automated/linux/wlan-smoke/wlan-smoke.yaml
