libdce[Android]: Add dce_ipc_recover API

In case of remote core recovery due to remote core crash, the rpmsg-dce
handle needs to be closed and re-opened since any handles that were
open when the crash happened are marked as stale in the driver.

This patch adds a new API that the user can call to close the rpmsg-dce
handle so that recovery can happen.

In case the user receives notification of a remote core crash, it can
call the dce_ipc_recover() API to make sure that the rpmsg-dce handle
that is opened during dce_buf_lock is closed so that a new one can
be opened the next time.
