libcamera: base: object: Prevent the same signal being connected more than once
Objects are not expected to be connected to the same signal more than once. Doing so likely indicates a bug in the code, and can be highlighted in debug builds with an assert that performs a lookup on the signals_ list. While it is possible to allow the implementation to let objects connect to a specific signal multiple times, there are no expected use cases for this in libcamera and this behaviour is restricted to favour defensive programming by raising an error when this occurs. Remove the support in the test framework which uses multiple Signal connections on the same object, and update the test to use a second Signal.
