tests: Bluetooth: Classic: Add test suites gap_discovery

Add test cases gap_central.test_01_gap_central_general_discovery and
gap_central.test_02_gap_central_limited_discovery.

Add test cases gap_peripheral.test_01_gap_peripheral_general_discovery
and gap_peripheral.test_02_gap_peripheral_limited_discovery.

+
+Bluetooth Classic GAP Discovery Test
+#####################################
+
+Overview
+********
+
+This test verifies the Bluetooth Classic GAP (Generic Access Profile) discovery
+functionality. It tests the device's ability to discover nearby Bluetooth Classic
+devices through inquiry procedures.
+
+Requirements
+************
+
+* A board with Bluetooth Classic support
+* Bluetooth Classic controller enabled in the configuration
+
+Building and Running
+********************
+
+This test can be built and executed on boards with Bluetooth Classic support.
+
+.. code-block:: console
+
+   ./tests/bluetooth/classic/gap_discovery/tests_scripts/gap_discovery_run.sh
+
+If the error "Permission denied" occurs, the following command should be used to add permission for
+the script.
+
+.. code-block:: console
+
+   chmod +x ./tests/bluetooth/classic/gap_discovery/tests_scripts/gap_discovery_run.sh
+
+If the error "west: command not found" occurs, the following command should be used to activate the
+virtual environment. Refer to :ref:`getting_started` for details.
+
+.. code-block:: console
+
+   source ~/zephyrproject/.venv/bin/activate
+
+Sample Output
+*************

+
+Test Coverage
+*************
+
+This test covers:
+
+* Bluetooth Classic initialization
+* GAP inquiry start/stop procedures
+* Device discovery callbacks
+* Inquiry result handling
+
+Configuration Options
