Support public_inputs in group targets

This change allows `group` targets to declare `public_inputs`.

When a target defines `public_inputs`, the files are treated as implicit
inputs of dependent targets (direct dependents and transitively via
`public_deps`).

Allowing `public_inputs` on `group` targets makes it possible to
aggregate generated files (e.g. `*.d.ts` declaration files, tsconfig
refs) and export them as public inputs to downstream consumers without
defining dummy stamp actions or creating self-dependency cycles in
actions.

I'd like to use this to simplify GN config like
