health package: switch to aidl HealthInfo

This is the first step of switching to AIDL health HAL. All
usages of HIDL HealthInfo is replaced with AIDL HealthInfo.

Because there's only one definition of HealthInfo in AIDL, all
3 versions of HIDL HealthInfo (1.0, 2.0, 2.1) are converted into
this AIDL HealthInfo.

A new function, Utils.copyV1Battery, is introduced in place of
Utils.copy, to denote that only battery fields in the V1 AIDL
HealthInfo are copied. When we add more battery fields to
HealthInfo in the future, the name V1 suggests that only V1
fields are copied. So we'll only need to change it to copyV2Battery
if we are going to use V2 fields in BatteryService.
