qcacmn: Add vdev feature flag for 20TU probe resp

6 GHz SAP needs to send either a probe response or fils
discovery at configured interval.  These in band
discovery frames can be disabled when lower band vdevs
are collocated with 6 GHz vdevs.

FILS disabled when lower band vdevs were up.
After vdev up send if WLAN_VDEV_FEXT_FILS_DISC_6G_SAP
is not set, host sending FILS command to enable 20TU.

Either driver or user not enabled 20TU probe response,
Host did not send the 20TU PRB RESP TMPL before sending
20TU PRB RESP enable command resulted Target assert.

Fixed this issue by adding 20TU vdev feature flag
and add appropriate check before sending command
to enable 20TU probe response.
