This patch extend TID configuration support to configure
RTS_CTS control and TX rate limit. Tx rate limit is
similar to auto rate but it will be limited to the user
configured rate mask rather than the station's highest
supported rate mask. Here ext_tid_cfg_bitmap added
to notify the target which extended configuration
parameter has modified(here RTS_CTS).

WMI_10_4_SERVICE_EXT_PEER_TID_CONFIGS_SUPPORT service flag
introduced to advertise this support.

Testing:
	* Tested HW: QCA9984
	* Tested FW: 10.4-3.9.0.2-00021
