This commit adds support to simplify sdcard.img generation by downloading the
latest bootloader build for a board from the 'latest-boot' release tag. The
tarball is saved in dl/bootloader/ and is extracted to a temporary directory
in output/build/boot-$board-xxxx on every invocation of mkimage.sh. This is
used for invoking genimage and bmaptool before copying the resulting images
to output/images/. (If $O is set, it is used instead of output/, above).
New options:
-d Download latest bootloader build for the given board
-f Force re-download even if bootlaoder tarball existgs

This commit consolidates mkimage.sh scripts into a unified SD card image
creation tool that works for all boards. It needs a bootloader an $ARCH
rootfs.squashfs image and a genimage.cfg.in template.
- Detects build directories from `O=` environment variable or `output/`
- Sources `.config` to discover Buildroot paths
- Uses Buildroot's `support/scripts/genimage.sh` when available
- Automatically generates `.bmap` files if `bmaptool` is available
- Fallback to direct `genimage` invocation if wrapper not found
See the online instructions for usage.
