Remove top level of indentation from type structure reports

[theunrepentantgeek]

What this PR does / why we need it:

Removes the top level of indentation from our structure reports, effectively moving type-names to the left margin.

Moving each type to the top level means reduced churn (smaller diffs) when a new type is added to a file.
