CaptureReplay: Emit unused resources

In the final frame of Manhattan, resources are cleaned up,
even if they are non-existent.  This is allowed by the GLES
spec.  Compilation of the replay would fail, for instance:

 error: use of undeclared identifier 'gRenderbufferMap';
        did you mean 'gFramebufferMap'?
        const GLuint glDeleteRenderbuffers_renderbuffersPacked_0[] =
            { gRenderbufferMap[0] };
              ^~~~~~~~~~~~~~~~

This is because we are only declaring resources if they are used.

Instead, go ahead and emit the resources, then circle back when
filtering is implemented, allow that to optimize the replay.
