feat(components): distinguish core processors from custom processors

[squakez]

PR to fix the behavior referred in CAMEL-23432 issue.

The main idea is to distinguish core processors from custom processors as the former should never be excluded during the generation of a telemetry trace, given that certain concrete telemetry technologies are instrumenting at a processor level.

• provide migration doc
• Implement camel-telemetrydev
• Implement camel-opentelemetry2
• Implement camel-micrometer-observability

TODO (separate PRs after merging this one):

• Add parameter in Camel main
• Add parameter in CSB
• Add parameter in CQ
• provide design doc (proposal)

Description

Target

• I checked that the commit is targeting the correct branch (Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally from root folder and I have committed all auto-generated changes.
