[C++] Use strong enum type for vectors when scoped-enums is on. (#5750)

Browse Source 
* [C++] Use strong enum type for vectors when scoped-enums is on.

These changes only apply when scoped-enums is on, and thus only
the C++17 tests show diffs.

This may break users who use 1) use scoped-enums and 2) use
vectors of enums.  However, it seems that this change should
have been made originally when scoped-enums were added.

Fixes #5285

* [C++] Put strong enum change also behind C++17 flag.

It actually only needs C++11 technically, but this is being done
to avoid breaking any existing users.

Tests were rerun, but produced no additional diffs, as expected.

* [C++] Forgot one location in which C++17 guard needs to go.

This commit produces no additional diffs in generated code.

* Use g_only_fixed_enums instead of scoped_enums.
