Keep the audio thread free of ended voices and too many vocoders (#356)
A song that had been played a few times in a long session stuttered
at regular intervals until the page was reloaded. A quick run up the
keys of a sampled instrument made every sound drop out for a second
or two. Both came from work the audio thread should not have had.

- Every worklet node of a voice listened on its port. Chrome never
  collects a port that is listened to, and through its listener not
  the voice either. Every node of the voice stayed on its bus and was
  worked on in every block. A way or stage on the worklet now closes
  its port once it ends or is stopped, and the processor closes its
  own side when it is told to stop.
- A voice without echoes now leaves its bus as soon as its sound and
  what its stages hold back are through. Before, only a voice with
  echoes did.
- At most 12 ways play through the pitch worklet at once. One more
  cuts the oldest in 10 ms, a note already let go before one still
  held. Each runs a phase vocoder, whose first block alone took
  2.7 ms of the 2.67 ms a block has on stein2.
- Play for the game ends everything the tabs play: the piece holding
  the transport and every key or preview (`stopPreviews`).
- Closing a Sound, Sound FX, Instrument, Pattern or Song tab stops
  what it plays of that asset (`AssetTabEditor.closed`).
- A preset in the Instrument tab plays nothing any more. With
  Audition on it is heard like any other change.
- Test hooks: `__gm.instrument.play`, `__gm.sound.playing`, and
  `vocoders` in the stats of the sound library.

Measured:
- A copy of the project, its Song 2 played for 12 s and stopped, six
  times (Chrome on stein2, CDP WebAudio): before, 746 nodes were left
  after the first time and 4469 after the sixth, the load at rest
  grew from 0.01 to 0.06. After, 7 nodes are left every time (the
  master and one bus) and the load at rest stays at 0.01 to 0.02.
- Pitch-player voices live in Chrome on melektaus-atx: 12 take 0.50
  of the audio thread, 16 take 0.71, 24 take 0.99. 30 struck 40 ms
  apart held it at 0.99 from the first second on.

Tests:
- Unit sound-library: 110 green (3 new), 4 counter-probes each red
- e2e 34 (melektaus-atx): ALL PASSED, 86 checks (3 new, 2 changed)
- e2e counter-probe with game start and preset undone: their 3
  checks red, and the old check of Play note in the game as well,
  which now counts on the preview being gone
- e2e counter-probe with tab close undone: exactly its check red. A
  first form of it held a key and stayed green, since the keys let go
  of a held key by themselves once the tab shows no asset
- Gate (melektaus-atx): 270 files, 4181 tests
