Fabiano Fidêncio f4d0ae1c2f docs: adopt guest-extension-image naming in composable-vm proposal
Align the composable VM images proposal with the naming convention used
throughout the implementation: the generic mechanism and its data model
are now "guest extension image" (config key `guest_extension_images`,
struct `GuestExtensionImage`), and the runtime artifacts use the matching
"extension" vocabulary (`/run/kata-extensions/<name>`,
`kata.extension.<name>.verity_params`, `kata-extension-mount@.service`,
the `extension-<name>` virtio-blk serial / dm-verity target, and the
`kata-containers-coco-extension.img` image).

It also documents how template-unit instances are enabled: a systemd
generator instantiates kata-extension-mount@<name>.service for each
extension on the kernel command line, so the rootfs build stays
extension-agnostic.

This replaces the earlier mixed "extra_images"/"addon" terminology and
addresses the naming-consistency review feedback on the series.
