It can be helpful to verify that the 'struct commit_graph' that results from parsing a commit-graph is correctly structured. The existence of different chunks is not enough to verify that all of the optional features are correctly enabled. Update 'test-tool read-graph' to output an "options:" line that includes information for different parts of the struct commit_graph. In particular, this change demonstrates that the read_generation_data option is never being enabled, which will be fixed in a later change.
