touch: init service to access gti interactive_calibrate sysfs
Write usage: setprop vendor.touch.gti0.ical VALUE
Any VALUE(e.g. 20X or 30X) set through this property will write
into gti interactive_calibrate sysfs except for the VALUE `read`.
Read usage: setprop vendor.touch.gti0.ical read
getprop vendor.touch.gti0.ical.result
setprop with VALUE `read` will read the gti
interactive_calibrate sysfs and save the result to
vendor.touch.gti0.ical.result.
Besides, please add your DOMAIN to access vendor_gti_prop.
set_prop(DOMAIN, vendor_gti_prop)
Bug: 331139251
Test: Manually verify the result.
