ElementAccessExpression and ArrayRankSpecifier edge cases

[belav]

There are a number of edge cases in VariableDeclartions.cst and one in FixedStatements.cst that are not handled yet. This is the desired formatting.

        var arrayCreationExpression1 = new byte[100];
        var arrayCreationExpression2 = 
            new byte[SqlParameterCollectionExtensions.DefaultValueColumnWidth];
        var arrayCreationExpression3 = 
            new byte[SqlParameterCollectionExtensions.DefaultValueColumnWidth + 100];
        var shortOne______ = 
            new byte[SqlParameterCollectionExtensions.DefaultValueColumnWidth + 100];
        var muchLongerOne_________________ = new byte[
                SqlParameterCollectionExtensions.DefaultValueColumnWidth + DefaultValueColumnWidth
            ];
        var muchLongerOne_________________ = new byte[
            SqlParameterCollectionExtensions.DefaultValueColumnWidth
            + SqlParameterCollectionExtensions.DefaultValueColumnWidth
        ];

        var elementAccessExpression1 = anArray[100];
        var elementAccessExpression2 =
            anArray[SqlParameterCollectionExtensions.DefaultValueColumnWidth];
        var elementAccessExpression3 = 
            anArray[SqlParameterCollectionExtensions.DefaultValueColumnWidth + 100];
        var shortOne______ = 
            anArray_[SqlParameterCollectionExtensions.DefaultValueColumnWidth + 100];
        var shortOne______ = anArray[
            SqlParameterCollectionExtensions.DefaultValueColumnWidth + DefaultValueColumnWidth
        ];
        var shortOne______ = anArray[
            SqlParameterCollectionExtensions.DefaultValueColumnWidth
            + SqlParameterCollectionExtensions.DefaultValueColumnWidth
        ];

// this is in FixedStatements
        int* someLongNameThatWillMakeThisBreakYeahKeepGoing_____________________ =
            stackalloc int[100];
