Univariate representation of variables in State Space Structural to match multivariate representation #536

Description

@Dekermanjian

As we work to add multivariate functionality to State Space the representation of structural component variables become non-scalar.

In the univariate case, however, we have certain variables that are scalar like auto_regressive_sigma which will have a shape of () and a Dimension of None.

In contrast, its multivariate counterpart will have shape (2,) and a Dimension of (auto_regressive_endog,).

Having a concrete value for the shape and a dimension could be intuitive for the end user and switching between univariate and multivariate models may be more parsimonious.

Would it make sense for the univariate case to follow suit such that the auto_regressive_sigma would have shape (1,) and a Dimension of (auto_regressive_endog,)?
