rosemary: libshim_sink: Port to U

* Since commit eb57617 [1], the legacy callback interfaces in the Android
  AudioTrack system have been deprecated and replaced by a newer callback
  interface. Consequently, the user parameter, which was previously part
  of the constructor, has been incorporated into this new interface.

* To address the resulting build issues, update the function signatures
  to match the new methods. Although AOSP provides a wrapper [2] for this
  purpose, it's declared within an anonymous namespace, effectively making
  it private to its own translation unit. To work around this limitation,
  provide a local copy of the wrapper instead.

* Also format the shim with `clang-format`.
