Preserve the type-as-written for bindings and use it in diagnostics. (#7804)

Browse Source 
In the `EntityName` for a binding, preserve the `TypeInstId` describing
how the type was written. When a diagnostic refers to that type via
`TypeOfInstId`, use the type-as-written in the diagnostic rather than
the canonical type.
