tcl/target: Added target configuration for Qualcomm QCS6490 IOT

Processors.

QCS6490 and QCM6490 are 6nm processors designed for enterprise and IOT
applications featuring global 5G and Wi-Fi 6E support with similar
architecture.

This configuration file will allow debugging applications on these
processors.

Verified with Olimex(ARM-USB-OCD-H):
openocd -f tcl/interface/ftdi/olimex-arm-usb-ocd-h.cfg 
-c 'transport select jtag' 
-f <path_to_qcs6490_cfg>

and Jlink:
openocd -f tcl/interface/jlink.cfg 
-c 'transport select jtag' 
-f <path_to_qcs6490_cfg>
