mmc: Update and remove functions for the kernel and rootfs

Add support for update and remove of eMMC images.

The code update tarball contains an image-kernel and image-rofs
files. These can be flashed directly to the eMMC partitions since
they're filesystem files compressed with zstd:

https://gerrit.openbmc-project.xyz/c/openbmc/meta-phosphor/+/30781
https://gerrit.openbmc-project.xyz/c/openbmc/meta-phosphor/+/34334

The image-rofs contains the BMC rootfs files, and the image-kernel
contains the fitImage file which is loaded by U-Boot.

Tested: Verified the non-running rofs and kernel partitions were updated.
