Missing `@when`, `@bool` blade directives

`@when` could be useful for conditionally printing things in general
```blade
<input name="phone" @when($isRequired, 'required') />
```

`@bool` allow boolean values to be printed directly into strings or used in object construction.
```blade
<script>
    let config = {
        isActive: @bool($isActive),
        hasAccess: @bool($hasAccess)
    };
</script>
```
