Revert "[build] Remove V8_GN_HEADER hybrid mode"

This reverts commit 6beed8d544.

Reason for revert: Breaks some targets that lack a dependency onto v8-gn.h, see https://crbug.com/1178409.


Original change's description:
> [build] Remove V8_GN_HEADER hybrid mode
>
> v8_generate_external_defines_header has been enabled for a couple of
> weeks now with no problems, so this removes the hybrid state where
> V8_GN_HEADER was defined on the command line along with the other
> defines.
>
