Updated unit tests in src/protocols/bdx/tests/ to use PW instead of NL. (#33084)

* Updated unit tests in src/protocols/bdx/tests/ to use PW instead of NL.

* Fixed clang and GN formatting. Moved BDXTests from test_components_nl.txt to test_components.txt.

* Used ASSERT_* in places where tests should be stopped immediately.  Refactored to get rid of else branches that did nothing but ASSERT_TRUE(false).

* Simplified TestBdxTransfersession::SetUpTestSuite as per PR suggestion.

* Undid the accidental reformatting of the comments at the top.

* Semicolon fix.
