ext_authz: expose fields latency, bytesSent and bytesReceived for CEL and logging (#37074)

This PR adds field access support for ext_authz filter state object
`ExtAuthzLoggingInfo`. It exposes simple fields
* latency
* bytesSent
* bytesReceived

This enables usage of ext_authz filter state in access logs, and any
filter/logger using CEL after
https://github.com/envoyproxy/envoy/pull/35698.
