Turn on eager-classloading (Camel 3.10) by default to optimize

In camel-main there is a new option

camel.main.eager-classloading = true

We can be a bit smarter in camel-quarkus, and so some kind of build step, that triggers invoking this eager classloading inside camel-main. This helps to ensure those classes are loaded during build time instead of runtime at the first message processed by Camel.

We need to ensure that this is triggered as part of quarkus and its built time phase so its triggered for both JVM vs native mode

Start by reading the camel-main eager-classloading option and the camel-quarkus build-step integration, then inspect how Quarkus build-time processing applies to both JVM and native mode. Done means eager classloading is triggered during the Quarkus build phase in both modes rather than on the first Camel message.
