qcacld-3.0: Add multi-client service bit caps and INI support

Add multi-client latency level service bit capability support,
WLAN_SOC_WLM_MULTI_CLIENT_LL_SUPPORT, to check whether the FW
supports multi-client latency level event or not.

Add INI "wlm_multi_client_ll feature" to enable/disable multi
client latency level feature from the host side.
 * @min: 0
 * @max: 1
 * @default: 0

If firmware sends multi-client latency level service
bit capability to host and host enables multi-client latency
level feature via INI, the host waits for an event
WMI_VDEV_LATENCY_LEVEL_EVENTID as a response to a request
command WMI_WLM_CONFIG_CMDID.
