Sync to upstream android-17.0 (AOSP17)

Pull in raspberry-vanilla's AOSP17 device tree changes for rpi5 while
keeping all PawletOS customizations (A/B partition layout, sepolicy,
zram, TWRP recovery scaffolding, ALSA HDMI pre-warm, product/overlay
structure) intact on top.

Upstream changes absorbed:
- AOSP17 audio HAL refactor (StreamAlsa split into StreamAlsaBase/
  StreamAlsaMonoPipe, Utils.cpp -> UtilsAlsa.cpp, new Bluetooth/stub
  helper classes, libeffects AIDL rebuild via *_ndk_shared defaults)
- API level 36 -> 37, FCM matrix level 202504 -> 202604
- QuickSettings tile default split (SystemUIRpiOverlay, ported into
  pawlet_rpi_common where this overlay now lives)
- vendor_tracing_descriptors added to enforce-product-packages-exist
- misc AOSP17 logging header switch (android-base/logging.h -> Log.h)
