This work is modeled on nodejs#30094 which allowed
`--disallow-code-generation-from-strings` in `NODE_OPTIONS`.

The `--jitless` v8 option has been supported since 12.0.0. As a v8 option,
node automatically picks it up, but there have been a few issues that were
resolved by simply telling users about the option: nodejs#26758, nodejs#28800.

This PR:
  - allows `--jitless` in `NODE_OPTIONS`
  - documents `--jitless`
  - moves `--experimental-loader=module` to locally restore alphabetical
    order in option documentation

v8 releases a new stable version roughly [every six weeks][], with the
schedule corresponding to releases of new chrome versions. v8 maintenance
of the previous stable version stops immediately, so Node.js minor versions
that pull in the latest stable v8 may have arbitrary changes.
