Updated unit tests in src/transport/tests/ to use PW instead of NL. (#33249)

* Refactored TestSecureSessionTable.cpp to use TestSecureSessionTable as the pw test context.

* Updated test_components[_nl].txt to move TransportLayerTests

* Fixed formatting

* Fixing merge conflict in test components nl

* Fixing merge conflict

* Updated TestSessionManagerDispatch to use staticly allocated context instead of dynamically.  Changed all tests to use XTestSuite instead of per-test SetUp/TearDown.

* Made context a non-pointer which is created/destroyed implicitly when each test case is run.

* Reordered includes to be consistent with the standard.
