rcar-gen3: Add RAUC packages

This adds RAUC and the related packages:

- Add sample keys and certificate.
- Add support for Renesas boards.
- Add rauc packagegroup.
- Add rauc_enable_fw_set to enable writing to eMMC boot1 partition.
- Backport u-boot-fw-utils v2108.09.
- Add U-boot sample script for boot slot selection.

To build RAUC packages with the current image, add
IMAGE_INSTALL_append = " rauc-packagegroup" to local.conf.
