@ViktorHofer, does it depend on dotnet/dotnet#2271?

[ViktorHofer]

Not necessarily but it would be better to get that in first. I included the branding update in this PR (see eng/Versions.props changes).

I updated the Apple mobile jobs to run on the scouting queues to get a clean run. The default queues are not functional at the moment. They will be fixed in a separate PR.

[kotlarmilos]

iOS mobile smoke tests passed.

tvOS is currently blocked by infrastructure issues that the engineering team is mitigating. I am reverting queue changes for now as they are in #122341.

For escaping build analysis please use dotnet/dnceng#6440

Let's try to push this through today if the failures are reasonable and can be worked in a follow up.

/ba-g only test failure is timeout

Same test is passing on MacOS in other configurations. Merging.

@DonnaChen888 once this flows to the dotnet/dotnet repo and we get a build, we should be able to update the global.json in dotnet/sdk and do the next two steps (update the templates to target 11 and update the SDK to target 11).
