Creates a `Controller` instance and performs short-running initialization
of all subcomponents.
Long-running initialization is performed in the Start() hook.
`sysmem` must be non-null.
`pci` must be non-null.
`resources` must be valid while the Controller instance is alive.
`engine_events` must be non-null and must outlive the created `Controller`
instance.

TODO(https://fxbug.dev/42164736): Consider making a fake IGD object injectable as allowing
mutable access to internal state that is intended to be externally immutable can be source of
bugs if used incorrectly. The various "ForTesting" methods are a typical anti-pattern that
exposes internal state and makes the class state machine harder to reason about.
