Use CamelCase in the 'WhereFilter' Template Calls

Got a request to change the name of the calls in the Jinja template for the
`WhereFilter` to use CamelCase to be similar to objects.

e.g.

```
{{ dimension('user__country', entity_path=['listing']) }} == 'US'

->

{{ Dimension('user__country', entity_path=['listing']) }} == 'US'
```
