feat: Add DirectAudio driver support

[joshuatam]

Description

Introduces DirectAudio as a new audio driver option for Wine.

This driver provides direct audio output to Android's AAudio, bypassing PulseAudio or ALSA middleware, potentially improving audio latency and compatibility for users.

Summary by cubic

Adds DirectAudio as a new Wine audio driver on Android, routing audio via AAudio to reduce latency by bypassing PulseAudio/ALSA. Supported only on Proton 11 arm64ec (Bionic); otherwise it auto-falls back to PulseAudio.

• New Features

  • Adds “DirectAudio” to audio driver settings (label: “DirectAudio (Proton 11 arm64ec only)”) and writes Wine registry Audio=directaudio.
  • Prevents selection outside Proton 11 arm64ec (Bionic) and auto-reverts to PulseAudio when unsupported or when Wine/variant changes.
  • Bundles updated directaudio-20260812.tzst with improved AAudio stream recovery and AAUDIO_USAGE_GAME (API 28+); ContainerManager.extractDirectAudio(...) installs winedirectaudio.drv and winedirectaudio.so into Wine and copies the .drv to the container’s system32 when DirectAudio is active.
  • Updates THIRD_PARTY_NOTICES with DirectAudio (LGPL-2.1-or-later).

• Migration

  • On Proton 11 arm64ec (Bionic), select “DirectAudio” in audio settings; the driver installs automatically. Others continue using PulseAudio.
