Original change's description:
> [build] Enable gn check for most of v8
>
> Currently there are 32 gn check failures across v8 (not including
> third_party). These are due to issues in cppgc and inspector, which are
> not trivially resolveable, so for now 4 targets (+ third_party) are
> being excluded from the checks.
