LibJS: Allow division after IdentifierNames in optional chain

Browse source 
The following syntax is valid:
```js
e?.example / 1.2
```

Previously, the `/` would be treated as a unterminated regex literal,
because it was calling the regular `consume` instead of
`consume_and_allow_division`.

This is what is done when parsing IdentifierNames in
parse_secondary_expression when a period is encountered.

Allows us to parse clients-main-[hash].js on https://ubereats.com/
