Adding python bindings for VtArray<SdfPathExpression> objects.

Description of Change(s)

Adding python bindings for VtArray<SdfPathExpression> objects.

Without these additions, it is not possible to use python to get or set attributes or metadata of type Sdf.ValueTypeNames.PathExpressionArray. There is obviously no pressing need for this as there are no schemas (that I am aware of) that use this data type, but since this is a valid data type, it seemed to me that it should be possible to use it in python.
