Set up sepolicy for CHRE HAL process

Contexthub (CHRE) team is removing the chre daemon and incorporating
its functionalities into the next gen HAL. This CL copied the
permissions we received in whitechapel/vendor/google/chre.te to
hal_contexthub.te to enable the same set of permissions on gs101.

Bug: 247124878
Test: launch the hal process on oriole and verify it can perform
required operations such as loading nanoapps holding wakelocks,
query nanoapps, etc.
