IndirectionType.none went away, but we were still using it in DataType.

Somewhat counter-intuitively, we can get an IndirectionType with a pointer depth of 0 and no reference flag set
So this PR adds a simple property to replace that none check (is_indirect)
This can then be used for the round-tripping of the data type
Added test coverage of the rule
