lib: add bt_field_class_get_graph_mip_version()

Add bt_field_class_get_graph_mip_version, which returns the MIP version
for the graph the field class is in, for the same reason as explained in
fbc90342dade ("lib: add bt_trace_class_get_graph_mip_version") for trace
class.

Note to Phil: I don't know where to put the function declaration in the
header, perhaps a new section is needed.
