test-read-graph: include extra post-parse info

Browse Source 
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.
