build: sync generation of v8_build_config.json

The contents of the `v8_build_config.json` file generated when
configured with `--enable-d8` is missing entries which prevent V8's
test runner from using the built `d8` binary. Sync the keys written
into the file with those generated in V8's `deps/v8/BUILD.gn` file.
