Pull request overview

Installs the Broadcom Vulkan ICD manifest into the gpu-layer bundled rootfs so Vulkan can be discovered/used from within the GPU layer for the RPI4 DAC 2.0 environment.

Changes:

• Conditionally installs broadcom_icd.arm.json into the gpu-layer Vulkan ICD directory when DISTRO_FEATURES includes vulkan.

• The install step hardcodes the Broadcom Vulkan ICD manifest name as broadcom_icd.arm.json. This makes the recipe brittle for other Raspberry Pi variants/architectures (the layer has a raspberrypi4-64 machine, e.g. recipes-kernel/android/android-raspberrypi.inc:20), where the staged ICD manifest filename may differ. Consider selecting the available broadcom_icd.*.json from the sysroot and installing it while preserving its basename.

        install -m 0444 "${STAGING_DATADIR}/vulkan/icd.d/broadcom_icd.arm.json" "${VULKAN_ICD_LAYER_DIR}/broadcom_icd.arm.json"

• There is trailing whitespace on the blank line after the Vulkan install block. Please remove the whitespace to avoid noisy diffs and style issues.
