Switch Dumpstate HAL policy to _client/_server

This switches Dumpstate HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Dumpstate HAL.

Domains which are clients of Dumpstate HAL, such as dumpstate domain,
are granted rules targeting hal_dumpstate only when the Dumpstate HAL
runs in passthrough mode (i.e., inside the client's process). When the
HAL runs in binderized mode (i.e., in another process/domain, with
clients talking to the HAL over HwBinder IPC), rules targeting
hal_dumpstate are not granted to client domains.

Domains which offer a binderized implementation of Dumpstate HAL, such
as hal_dumpstate_default domain, are always granted rules targeting
hal_dumpstate.
