Refactor icons: harmonize contextually, use filled status icons

[pat-s]

Follow-up to #4414 which started to use the outline icon-set for the pipeline status icons.

• Harmonized status icons to use circleFilled icons
• Harmonized other contextual sub-groups to use outline icons
• Squash alert/error/warning icons to a single icons and distinguish by color

This is another all or nothing discussion:

• all icons should be used from the same library
• all semantically related icons (e.g. all pipeline status icons) should use the same style
• NOT all used icons need to use the same style (just because pipeline status icons are outlined doesn't mean everything need to be outlined)

To me, there is no need to use ALL outlined icons whenever possible. But this time I'll leave the decision to someone else 😃 Personally, I don't like the octagon icons.

@pat-s what do you think about alert-circle-outline for the linter tab instead of the octagon icons?

[pat-s]

Fine with me. Overall I am wondering if there should be different icons for error and warning.

[xoxys]

If we stick with different colors, I don't think it's necessary. Do you have an idea for different icons?

[pat-s]

Maybe mdi:stop-circle-outline in red for errors and mdi:alert-circle-outline in yellow for warnings

[pat-s]

Yeah it doesn't fit so well. I think my thought was wrong.

So now, h-8 w-8 paired with 1.3rem. Is that good for everyone?

[xoxys]

While it might make sense to use w-8 h-8 instead of -9 how is this related to the default size of the icons? Changing them to 1.2rem will not make them fit with the default line height of 24px. Would just like to understand how to use the 8-point grid correctly.

[pat-s]

Can we outsource this into a discussion/chat?

[xoxys]

@pat-s I did the remaining cleanups:

• remove duplicate icons with the same target but different name
• harmonize pipeline log icons
  
• dont re-use the download icons for scroll/no-scroll and replace it with the eye icon variants

I hope it was ok to push to your branch. If not please feel free to revert. Please re-check, if you dont have anything to add we are good to go now.

[pat-s]

Thanks cleaning up and all the feedback! Much appreciated.

Now we have merge conflicts again 😐
