Allow [Immutable] for function parameters as well

Link to original bug (#539703)
Description
If the C API declares a parameter as 'const' for non-immutable objects, there is no way to tell Vala to honor that. Allowing [Immutable] for function parameters should be a good way of telling binding generator to honor that. An example is Gst.TagForeachFunc where the list parameter should be declared as 'const'.
