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.
