dumpstate: Call dumpstate HAL HIDL and AIDL APIs

- Call dumpstate HAL AIDL, if found, else call dumpstate HAL
  HIDL APIs since it is expected that in a given device only
  HIDL or AIDL will be implemented
- Remove dumpstate_hal_mode from DumpState::DumpOptions
  and use bugreport_mode since HAL dumpstate mode enum
  can be different in HIDL vs AIDL.
