Don't expose `ChooserTarget` from `TargetInfo` API.

`ChooserTarget` is a deprecated API left over from the (now long-gone)
`ChooserTargetService` system, but internally, `SelectableTargetInfo`
still relies on this type for some basic record-keeping. The
`ChooserTarget`s today come from two sources; they're either passed in
from the caller via `EXTRA_CHOOSER_TARGETS`, or synthesized internally
to shoehorn non-`ChooserTarget` data into a `SelectableTargetInfo`.

Prior to this CL, clients throughout the application might reach
through to the composed-in `ChooserTarget` for some fields stored in
that record type. After this CL, any fields accessed in that way are
instead lifted to the `TargetInfo` API so that clients can access them
directly, without going through a `ChooserTarget`. Thus "consuming"
clients don't need to be aware of the `ChooserTarget`, and from their
perspective it's an internal implementation detail of
`SelectableTargetInfo`.

In a first subsequent CL, these fields can be precomputed from the
`ChooserTarget` during the construction of the `SelectableTargetInfo`
so that we don't retain any instances once we've extracted the
relevant data. In a second subsequent CL, we can expose those fields
as initialization parameters; then instead of synthesizing
intermediate `ChooserTarget`s, we can build our synthetic targets as
`SelectableTargetInfo`s directly. The usage in `EXTRA_CHOOSER_TARGETS`
is regrettably part of our public API that was overlooked in the
`ChooserTargetService` deprecation and won't be going away any time
soon, but if we can adapt them to the `SelectableTargetInfo`
representation immediately when we read them out of the request, we
should be able to cut out any other remaining references to
`ChooserTarget`.
