Sync eng/common/{cross,native} with arcade

[am11]

It stopped syncing automatically few months ago for some reason, so new platforms' configs aren't showing up. See #5858 (comment).

cc @hoyosjs, @akoeplinger it includes dotnet/arcade#17027.

@am11 - have you noticed this in other repos? And is it just these dirs?

Yup, in SDK and aspnetcore. Up until last month, only runtime and diagnostics were using native infra from eng/common. Now that aspnetcore and SDK tools are AOT published for few weeks, we should sync the entire eng/common without any filtering across arcade-powered repos. IMO, it's much simpler (and it seems like the original intent when eng/common/README.md file was first written..).

And is it just these dirs?

Just copied the entire dir, pushed a commit. Seems like there was more out of sync, so something is filtering the contents. :/

@hoyosjs, turned out additional changes in new eng/common required new dotnet download command which is available in SDK 11.0, so I first merged #5858 to this PR, then updated global.json to 11.0. Note that this is just a "build toolchain" version, it doesn't change <TargetFramework of individual projects.

We can't use .NET 11 SDK in this repo - we use the release branch of arcade

[hoyosjs]

We use the arcade 10 branch

[hoyosjs]

10.0.3xx also has the feature - but I believe it might not be available in source build

@hoyosjs, the MicrosoftDotNetArcadeSdkPackageVersion still points to v10 in this PR. The only thing which has bumped is the toolchain which is capable of handling more versions beyond v10. That should not have any impact on the final product (it still uses the same libraries versions to build the product). If this is a problem, let me know and i will reset to the original shape of PR: sync only eng/common/{cross,native} sub-dirs.
