Change ast::Array to use an ast::Expression for its `size` field. The WGSL frontend now parses the array size as an `primary_expression`, and the Resolver is responsible for validating the expression is a signed or unsigned integer, and either a literal or a non-overridable module-scope constant. The Resolver evaluates the constant value of the size expression, and so the resolved sem::Array type still has a constant size as before.
