The feature was never finished (crbug.com/911799), but adds a
build-time dependency on the trunks proto in platform2.

This adds a new disk file type next to raw files and qcow images that
represent an indirection to further raw disk files. The disk file
itself is a proto file with references to file paths for other disks to
open and their virtual offsets and lengths.
The intention is to make it easy to assemble a single virtual hard disk
out of several distinct partition files. In the particular case of
Cuttlefish running Android in a VM, this is relevant as the Android
build system distributes partitions as separate raw files. While the
simple solution is to pass each partition as a separate raw disk, some
functionality (like the bootloader) assumes there is a partition table
with multiple distinct partitions on a single disk.
Implementing composite disk support in the VMM bridges this gap through
supporting the general-purpose case of a disk built out of multiple
component files.
If desired, this can be extended to support qcow files to support
unusual configurations like a mixed qcow/raw disk.
Enabled with the "composite-disk" feature.

This de-duplicates the two separate build.rs files dealing with proto
compilation. The trunks interface.proto will be exposed under
protos::trunks and the plugin proto will be exposed under protos::plugin.
