qcacld-3.0: Pkt capture config for qos null and trigger frames

Provide ucfg api to configure qos null and trigger frames.

Ucfg api will send configuration to FW. Below configuration values
are allowed.

PACKET_CAPTURE_CONFIG_TRIGGER_QOS_DISABLE: disable capture for
trigger and qos frames.
PACKET_CAPTURE_CONFIG_TRIGGER_ENABLE: enable capture for trigger
frames only.
PACKET_CAPTURE_CONFIG_QOS_ENABLE: enable capture for qos frames only.
PACKET_CAPTURE_CONFIG_TRIGGER_QOS_ENABLE: enable capture for both
trigger and qos frames.

The packet capture config old value will be over written by new value.
For example, first if we configure value as
PACKET_CAPTURE_CONFIG_TRIGGER_ENABLE and then if we send config as
PACKET_CAPTURE_CONFIG_QOS_ENABLE then config is enabled only for qos.
