Compositor automated testing

Added support for compositor tests. Compositor tests can be added, executed and viewed in a similar way to cycles
and other render engines tests.

Running test:
`ctest -R compositor`

Updating test:
`BLENDER_TEST_UPDATE=1 ctest -R compositor`

Viewing test results:
typically saved under `build_folder/tests/compositor/report.html`
