Do not fail Rolling jobs on deprecations

[nbbrooks]

Description

Unfortunately, the timing+pace of rolling deprecations is outpacing the ability to address them with our current set of active maintainers and contributors. Originally we configured CI jobs to fail on deprecations to force us to fix them, but at this point, often when we go to fix them, there are several simultaneous deprecations from various upstream sources which requires one of the following to happen

• A mega PR (examples Fix deprecations in image_common and tf2_ros #3567 and Qt6 compile fix #3493) that addresses all deprecations simultaneous
• A targeted PR for a single deprecation but large reviewer burden to locally build the PR against each supported distro since the CI jobs short circuit (and an override of CI to merge the PR)
• Fingers crossed merge with CI failing rather than a large review burden (and an override of CI)

This is not sustainable anymore (and promotes huge PRs that are tough to review), so what I'm doing in this PR is:

• Add '-Wno-error=deprecated-declarations' to mandatory Rolling CI jobs.
• Add new, currently optional CI Rolling job that does fail on deprecations

Depending on the state of upstream deprecations maintainers can change the state of this new, currently optional CI Rolling job that does fail on deprecations. But for now I would like to unblock community contributions while we address the current set of deprecations.

Checklist

• Required by CI: Code is auto formatted using clang-format
• Extend the tutorials / documentation reference
• Document API changes relevant to the user in the MIGRATION.md notes
• Create tests, which fail without this PR reference
• Include a screenshot if changing a GUI
• While waiting for someone to review your request, please help review another open pull request to support the maintainers

Force merging this - the required Rolling jobs are failing due to lack of Qt6 support. The new optional rolling deprecated job is failing as expected due to deprecations.
