test: add test: jack detection if DSP is in D3

Add a new test case to test jack detection during
DSP is in D3 state. The test will check if the jack
detection status is updated correctly when the jack
is plugged in and unplugged and also if DSP status
is changing correctly as well.
For unplug/plug headset jack is using a USB relay.

+## Preconditions
+# USB relay switch is available and configured.
+# Jack detection header should be connected to the USB relay switch
+# to the port HURTM_2 (NC) connector.
+
+## Test Description
+# Verify jack detection functionality by simulating plugging and unplugging
+# of audio jack using a USB relay switch.
+# The unplugging and plugging of the jack is when DSP is in D3 state (suspend)
+# to ensure the system can handle jack detection events correctly.
+# The test will check if the jack detection status is updated correctly
+# when the jack is plugged in and unplugged and if DSP status is changing
+# correctly as well.
