    Original change's description:
    > [snapshot] Add support for native counters.
    > 
    > Counters in generated code, as enabled with --native-code-counters, do not work
    > in the snapshot. This adds a `v8_enable_snapshot_code_counters` build option
    > enabled by defaut in debug mode that allows code from the snapshot to increment
    > the current isolate's set of counters.
    > 
    > For this to work, we need to add native code counters in the external reference
    > table.
    > 
    > To keep the no snapshot configuration similar, we've also enabled the
    > --native-code-counters flag by default for debug builds.
