battery: raviole: disable wireless for pts battery test

Disable wireless charging during drain, usb charging,
and charger stress test
  - vendor.disable.wlc 1
If device put onto dreamliner and shutdwon(drain out),
it would boot up by DC_CHG and keep shutdown(0%)-boot up
(by DC_CHG) continously. To avoid this symptom, limit wireless
current_max as 75000 after device boot up
  - persist.vendor.limit.wlc.current=1

How to verify:
  adb shell setprop vendor.disable.wlc 1
  adb shell cat /sys/class/power_supply/wireless/online >>>> 0

  adb shell setprop persist.vendor.limit.wlc.current 1
  adb shell cat /sys/class/power_supply/dc/current_max >>>> 75000

Bug: 179094447
Test: set the property manually and query the result from file node.
