healthd: start using the new Health hal
Subsequently moves the default board hooks to hardware/interface/health
where the new HAL is defined.
This change removes 'healthd's dependency on libhealthd.<target> static hal.
The dependency has now been *temporarily* moved to the new HAL
implementation in hardware/interfaces/health. 'charger' continues to depend
the static HAL.
Test: Tested healthd with and without a board specific health HAL on
Angler.
