Issue:
Support serving binary data from ConfigMap
Hi and thank you for looking into this.

*Description*:
>Describe the desired behavior, what scenario it enables and how it
would be used.

At the moment, Envoy Gateway only supports text data as custom responses as defined in https://gateway.envoyproxy.io/docs/api/extension_types/#customresponsebody. However, there are clear use cases where it is necessary to support sending binary data. 

Our use case is to serve a static favicon.ico from binary data injected into the `binaryData` section of a ConfigMap, in the same way as it supports text data in the `data` section. The `binaryData` could serve simple binary canned responses that it would load from base64-encoded `binaryData` sections of a ConfigMap.

At the moment, the `binaryData` section of ConfigMaps are ignored by Envoy Gateway, and base64 encoded strings are served as-is (as would be expected) as text from `data` sections

Need to just check out few things on the xDS side
