You could move the Piano_pedal_performer from Voice to Staff level. Add 
or remove the \consists command to hear the difference.

\version "2.20.0"

\midi {
    \context { \Voice \remove Piano_pedal_performer }
    \context { \Staff \consists Piano_pedal_performer }
}

upper = {
  <<
    {c'8\sustainOn r r}
  \\
    {r8 r r}
  >>

  <<
    {r8 r r}
  \\
    {r8 r c'\sustainOff}
  >>
}

lower = { s1 }

\score {
  %{ \new PianoStaff %} <<
    \new Staff = "upper" \upper
    \new Staff = "lower" \lower
  >>
  \layout { }
  \midi { }
}
