gh513 Change videodevice_term to last

[hjourdain-ryvr]

For the VideoDevice tests to be successful, they need to be run after videodevice_init and before videodevice_term. Currently, videodevice_term is called just after videodevice_init in the test suite. Move it to the last position.

Since this is an L3 test, the order of test cases doesn’t matter because the host/Python script controls the execution sequence

[hjourdain-ryvr]

If you run the test suites manually, you can select the test suite to run, then run all the tests in it automatically. I believe you can do the same with automated testing.
With this test suite, if you do that with the current order, then the test suite will fail, because term is called before some of the tests in the test suite are run, therefore the tests after that in the test suite will not be initialized - and the tests are not "self-contained" (they do not call the module init/term as part of the test).

The purpose of the VTS is also to provide a scope for the developer who may need to debug. The L3 tests can run in steps if required by selecting the init, any action-related api, and term in the necessary sequence. If we need to run this in automation, we also use the tests available in tests, which are already sequenced. Refer to https://github.com/rdkcentral/rdk-halif-test-device_settings/tree/main/host/tests/L3_TestCases/dsVideoDevice for the tests in sequence.
