[SPARK-11819][SQL] nice error message for missing encoder
before this PR, when users try to get an encoder for an un-supported class,
they will only get a very simple error message like `Encoder for type xxx is
not supported`.
After this PR, the error message become more friendly, for example:
```
No Encoder found for abc.xyz.NonEncodable
- field (class: "abc.xyz.NonEncodable", name: "a")
- field (class: "abc.xyz.MyClass", name: "b")
- root object (class: "abc.xyz.AnotherClass")
```
