ES6 Literal Template Support inside GSP Pages

The following will not work inside a gsp and will throw an exception.
```html

const name = 'Bob';
console.log(`Hello ${name}`)

```

Workaround:
```html

const name = 'Bob';
console.log(${raw('`Hello ${name}`')})

```

but a workaround shouldn't be necessary if 1. currently in a block AND inside ``.

Start by reproducing the example in a GSP page containing a script block and an ES6 template literal, then inspect the GSP template parsing path. Done means the literal works inside script blocks without requiring the raw() workaround; no specific source file or test is named in the issue.
