The TypeDef table view derived FieldList/MethodList from the computed
member ranges (TypeDefinition.GetFields/GetMethods), and the MethodDef
view derived ParamList the same way; their FirstOrDefault is a nil
handle for an empty range, so memberless types and parameterless
methods displayed row 0. The stored column value is never 0: it is the
running list position, i.e. the next row's first member or one past the
member table's end. Read the raw columns instead, relative to the row
end so the widths of the preceding string-heap, blob and coded-index
columns need not be re-derived, and sized by the table the column
actually indexes (the FieldPtr/MethodPtr/ParamPtr indirection when
present). EventMap and PropertyMap already read their list columns from
the raw rows. Tooltips explain the empty-list-start semantics; rows
with members behave as before.
