  [mlir] Change end of OperationDefinition. (#77273)

Store the last token parsed in the parser state so that the range parsed
can utilize its end rather than the start of the token after parsed.
This results in a tighter range (especially true in the case of
comments, see

```mlir
|%c4 = arith.constant 4 : index

  // Foo

  |
```

vs

```mlir
|%c4 = arith.constant 4 : index|
```

).

Discovered while working on a little textual post processing tool.
