Remove remaining `dart:developer` Timeline usage from flute

When compiling flute with

  % dart compile wasm -Ddart.vm.product=true benchmarks/lib/complex.dart

we see that the mjs file will now have the following lines removed

  ```diff
  -      _182: () => globalThis.performance,
  -      _183: () => globalThis.JSON,
  -      _184: x0 => x0.measure,
  -      _185: x0 => x0.mark,
  -      _186: x0 => x0.clearMeasures,
  -      _187: x0 => x0.clearMarks,
  -      _188: (x0,x1,x2,x3) => x0.measure(x1,x2,x3),
  -      _189: (x0,x1,x2) => x0.mark(x1,x2),
  -      _190: x0 => x0.clearMeasures(),
  -      _191: x0 => x0.clearMarks(),
  -      _192: (x0,x1) => x0.parse(x1),
  ```

This mirrors the change in real flutter from
