CAMEL-18757 Specify type for pom-only artifacts like camel-*-parent

https://issues.apache.org/jira/browse/CAMEL-18757

Check the model of each component for the packaging type. If a pom, express that in the parent and the bom.

Did some parent/pom.xml cleanup as well - I checked through the entries for core, dsl, and catalog and added dependency entries for any missing artifacts under those sections. Fixed some spacing issues in parent/pom.xml generation.

I wonder if maven plugins such as

 <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-vertx-kafka-maven-plugin</artifactId>
        <version>${project.version}</version>
      </dependency>

Should have

<type>maven-plugin</type>

https://maven.apache.org/ref/3.8.6/maven-core/artifact-handlers.html

A plugin has

 <packaging>maven-plugin</packaging>

Can definitely make that change but in the other projects that I've checked (cxf, karaf) the type isn't included in the bom for maven-plugin. The reason I'm keen to make this change is that the lack of <type>pom</type> is an issue for parent dependencies because no jars exist for that dependency - and it causes errors on certain bom resolution programs that default to looking for a jar. In the case of maven-plugins, a jar definitely exists.

Okay its fine if others dont do that - also I dont think its a real problem, for end users that import this BOM
