oxmc ff34391e4b rpi5: partition layout, boot setup, slow_storage, BootControl, wrimg for Android 16 
Partition layout:
- BoardConfig: system 8 GB, vendor 2 GB
- mkimg: matching system/vendor partition sizes
- fstab: remove discard from metadata; make discard opt-in via
  BOARD_STORAGE_SUPPORTS_DISCARD to avoid boot-time I/O stalls
- wrimg: grow userdata to fill remaining device space on flash

Boot:
- mkbootimg: use stamp file for rpiboot; uppercase FAT volume label
- rpi5: set androidboot.boot_devices for by-name symlink creation
- wrimg: stamp androidboot.slot_suffix in cmdline.txt after each A/B write
- rpi5: disable AVB (no vbmeta partition in this layout)

A/B / BootControl:
- sepolicy: add BootControl HAL policy and fix partition file_contexts
- wrimg: switch to PARTLABEL-based device detection; fix system_ext brackets

Initial repo setup:
- Separate into standalone pawlet_rpi5 repository
- Disable recovery/TWRP; fix include paths and package names
- Align to upstream KonstaKANG rpi5 base
