Supported platforms: Improving and defining CI related verification task

Issue (and solution) in CI side:

• CI knows what is tested in CI and can make that more visible and verified
• We have versions updated in versions.txt, but some information is missed and has to find it in different ad-hoc/specific ways
• What we are missing, is to link the request (Supported platforms needs info) to the data we store (versions.txt) and verify it exists

Improvement to define CI scope in Supported Platforms -page:

• Needs to define where CI information/knowledge is usable at Supported Platforms -page, because there's information which is better checked by other relevant stakeholders as well
• And alternatively improve also visibility of that information collected from logs, if needed by others

Proposal for relevant CI scope to check in this task:

• 1) Desktop Platforms
• 2) Mobile Platforms
• and improve + verify requested compiler versions etc. visibility in versions.txt
• Request = info which is needed in Supported Platforms -pages
