Combine Azure support extension logic into a single `camel-quarkus-support-azure` extension

Currently we have:

* `camel-quarkus-support-azure-core`
* `camel-quarkus-support-azure-core-http-client-vertx`

I was considering creating a new 'support' extension for `azure-identity`. But, given the logic in these extensions applies to all of the Camel Azure component extensions, it probably makes more sense to combine it all under a single `camel-quarkus-support-azure` module.
