Revert "Forward fix jni_generator_helper.h."

This reverts commit 63e83c77ae81730a78ec4d5bf0465f25970f867a.

Reason for revert: JNI generator is not using the heap profiler
anymore.

Original change's description:
> Forward fix jni_generator_helper.h.
>
> In crrev.com/531028, the JNI generator starts to add heap profiler
> events to JNI generated functions.
>
> This will cause a ~80KiB regression and at the moment it is breaking
> the Chromium Roll into WebRTC.
>
> This CL defines a void macro to re-enable the Chromium Roll avoiding
> the size regression.
>
> Bug: chromium:801260
