Updated unit tests in src/transport/raw/tests/ to use PW instead of NL. (project-chip#33099)

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

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

* Updated unit tests in src/transport/raw/tests/ to use PW instead of NL.

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

* Update src/transport/raw/tests/TestTCP.cpp

Co-authored-by: Arkadiusz Bokowy <arkadiusz.bokowy@gmail.com>

* Update src/transport/raw/tests/TestUDP.cpp

Co-authored-by: Arkadiusz Bokowy <arkadiusz.bokowy@gmail.com>

* Changed some EXPECT_ to ASSERT_.  Changed C-casts to unsigned literals.  Chagned strcmp to EXPECT_STREQ.

* Resolved merge conflicts in test_components[_nl].txt

* Added a destructor to TestUDP to delete the TestContext.

* Added destructor to TestTCP to delete the TestContext.

* Added destructor to TestTCP to delete TestContext.

* Fixed issue with SystemLayerTests being listed multiple times.

* Changed MemoryInit line to ASSERT instead of EXPECT.  Added corresponding MemoryShutdown.

* Inherited TCP test from IOContext so we don't have to create a new context.

* Moved ChckSimpleInitTest and CheckMessageTest into the test context class.
