thermal: support usb overheat protection

Browse source 
Base on EVT 1.0 test result to support the USB thermal protection
1. When usb_therm > 46 degC start monitor
2. When usb_therm - charger_therm >= 10 degC, change usbc-port to 1
3. When usb_therm - charger_therm >= 13 degC, trigger VIRTUAL-USB-UI
   polling
4. When usb_therm - charger_therm <= 7 degC, change usbc_prot to 0

Create thermal config for proto to prevent wrong usb throttle on proto
device

Bug: 278035350
Test: push the test script into device and run thermal_recorder to
record the behavior. Detail is in the bug
