samples: nrf_rpc: ps_server: RPC alive LED

[Damian-Nordic]

1. Add nrf_rpc_uart_initialized_hook() that is called when an nRF RPC UART transport instance gets ready to receive packets.
2. Use the hook in the PS server sample to toggle the LED selected with /alias/rpc-alive-led DTS property when the RPC transport is ready.

[nordicjm]

this is not how callbacks are done in zephyr but will approve anyhow

[Damian-Nordic]
