tests: Bluetooth: Mesh: Op_agg coex loopback test

Adds coexistence Bsim test for Opcode Aggregator models using loopback. The test verifies that the Opcode Aggregator server and client can send messages to each other on the loopback interface. Signed-off-by: Anders Storrø <[email protected]>

+# Test that an Opcode aggregated message can be sent and received on loopback.
+#
+# Test procedure:
+# 1. The device initializes both Opcode aggregator server and client.
+#    The device starts an Opcode aggregator sequence and populates the buffer.
+# 2. The device starts sending the sequence on loopback.
+# 3. The device verifies that the sequence is correctly received by the server model.
+# 4. The device confirms that the client model received all status messages.
