CL:1385972 breaks building these crates because they are not in the
workspace of the top level Cargo.toml so the patch.crates-io setting of
the top level Cargo.toml does not take effect. They end up looking for
their dependencies on crates.io rather than in the parent directory.
Being able to build just data_model and sys_util on their own is useful
when iterating on a change in one of them and needing to run `cargo
test` (as I tried to do today). The errors without this CL are like
this:
error: no matching package named `assertions` found
location searched: registry `https://github.com/rust-lang/crates.io-index`
required by package `data_model v0.1.0 (/path/to/crosvm/data_model)`

Split sub-crates under crosvm root directory into several independent
workspaces for adding ebuild files for those crates.
data_model and sys_util could only be built by emerge after creating
their ebuilds.

This depends on the `assertions` crate added in CL:1366819.
`const_assert!(boolean expression)` is a compile-time assertion that
fails to compile if the expression is false.
TEST=`cargo check` each of the modified crates

The data_model crate is created to hold the DataInit trait. Types
implementing this unsafe trait must guarantee that the type can be
initialized with random data and the resulting object will be valid.
