tests: camerabin: add tests for GstPhotography image capture
GstPhotography enables new paths in wrappercamerabinsrc that allows the source to be notified about the capture caps and provide an alternative caps if desired bypassing the negotiation (this doesn't seem like a good idea these days). To make sure it keeps working until we remove it from the API in favor of standard caps negotiation features this test was added. It adds 3 extra tests with a simple test source that will: 1) Test that capturing with ANY caps work 2) Test that capturing with a fixed caps work 3) Test that capturing with a fixed caps and having the source pick a different resolution from GstPhotography API works by having wrappercamerabinsrc crop the capture to the final requested dimensions
