feat(tools): ship metadata, IO and BL files on SD card

This pushes the metadata files as well as the IO firmware and the
bootloader binary to the SD card.
That way, the files are don't have to be added to the firmware
binary or served via s3 for FLASH_CONSTRAINED targets.

The files are pushed after upload and verified in commander as part of
the preflight checks. If missing, a warning is displayed and arming is
prevented.

This means that an SD card can't be swapped out without reflashing (or
copying over the contents).
