Make invalid & operator type error message consistent with */**
If #to_proc is defined, this uses the following error message format,
matching the error message format used for * when to_a returns non-Array
and for ** when to_hash returns non-Hash:
```
can't convert ClassName to Proc (ClassName#to_proc gives OtherClassName)
```
If #to_proc is not defined, this uses the following error message format,
matching the error message format used when ** is called on a non-Hash
not implementing to_hash.
```
no implicit conversion of ClassName into Proc
```
There isn't a similar error for * when called on a non-Array not
implementing to_a, as Ruby does not raise for that case.
Fixes [Bug #21563]
