Dana Jansens ed43fd2c1c Give the BindSymbolicName for .Self in a binding pattern a FacetType type (#6036) 
If it's just `TypeType` then the `BindSymbolicName` appears directly in
type positions, but if it is replaced with another facet value, then we
would need to insert a `FacetAccessType` around it. By giving it a
`FacetType` type, like other `BindSymbolicName`s we make it consistent
and avoid having to introduce extra instructions.
