[cleanup] Removing GraphBuilderTester class

GraphBuilderTester was introduced at a time where RawMachineAssembler
was going to be deprecated (https://codereview.chromium.org/1423923003/).
Now we know that it's not going to happen any time soon.

Since GraphBuilderTester it's only used in one test which can use
RawMachineAssembler, I updated it and removed the class.

Now the .h file had another class, which is now the only class in the file.
Therefore, I renamed it and updated the include calls to it.

Also updated the include commands: some were not necessary, and some others
could be moved to more aptly places.
