ANDROID: thermal: Add vendor thermal genl check

Browse Source 
Add vendor enable_thermal_genl_check logic.
Filter on-die tz genl event.

To avoid thermal-hal being woken up all the time by thermal genl events,
only the selected thermal_zone and cooling_device can send events from
kernel.

Bug: 170682696
Bug: 291846209
Test: boot and thermal-hal can receive thermal genl events from kernel
