Antalya 26.3 - Use regression runners for smaller checks jobs [CI Cost Reduction]

[strtgbb]

Changelog category (leave one):

• CI Fix or Improvement (changelog entry is not required)

Changes

• Simplify the the rebase diff in job_configs.py
• "Medium" jobs now run on regression runners for x86 instead of func-tester
• "Small" jobs now run on regression runners for x86 and ARM instead of style-check
• Install check is now "Small" instead of "style check" or "func-test"

Regression ARM runners are in short supply so have not been used for "Medium" jobs.
"Small" jobs are bigger than "style check" jobs, which is why they have been upgraded.
