Expand the rpi family example from a single bookworm/drm-kms-egl board into the
six targets the ivi-homescreen PiOS CI needs: {rpi5, rpi4, rpi-zero-2w} x
{bookworm, trixie}.
- OS variant drives toolchain + sysroot (and thus the container image):
bookworm -> 12.3.rel1 + raspios-bookworm; trixie -> 15.2.rel1 + raspios-trixie.
bookworm cross-builds libdisplay-info 0.2.0 (ships 0.1.1, drm-cxx needs >=0.2.0)
and omits the apt libdisplay-info-dev so the static .a isn't shadowed; trixie
keeps it. Vulkan headers are vendored by ivi-homescreen + drm-cxx, so neither
OS stages them.
- Board only changes -mcpu (a76/a72/a53); all three share one sysroot per OS.
- Backends: rpi5 builds all five (incl. drm-kms-vulkan); rpi4 and zero-2w build
the four without it. Plugins on (PLUGINS_DIR=../ivi-homescreen-plugins).
Validated: parses, --list-targets shows the right per-model backend sets, and
--dry-run resolves each target's toolchain/image/cpu/augment. Example tests pass.
