Add no metrics state for compare runs metrics section

[DaoDaoNoCode]

JIRA: RHOAIENG-8406

Description

Add an empty state when there are runs selected but no metrics to compare for all the tabs in compare run metrics section.

How Has This Been Tested?

1. Create some runs with a pipeline that will not generate metrics
2. Go to compare runs page
3. See the metrics section, check and uncheck the runs
4. Make sure the empty state is shown as described

Test Impact

Added some cypress tests to verify the empty state

Request review criteria:

Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work
• Commits have been squashed into descriptive, self-contained units of work (e.g. 'WIP' and 'Implements feedback' style messages have been removed)
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit or cypress tests for related changes)

If you have UI changes:

• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change (find relevant UX in the SMEs section).

After the PR is posted & before it merges:

• The developer has tested their solution on a cluster by using the image produced by the PR to main
