Generate a constructed EEType for constrained tokens (#5437)
`CorInfoTokenKind.CORINFO_TOKENKIND_Constrained` means RyuJIT is asking for a type handle with the purpose of boxing it.
This fixes:
```csharp
struct Foo { }
void Main() { Foo f = default; f.GetHashCode() }
```
We were trying to execute bogus memory because unconstructed types don't have vtables.
