Remove src/arcade/eng/common from repos that took it

[dkurepa]

Because of #4751 (comment), there was a number of repos that took a dependency update from the VMR and accidentally added src/arcade/eng/common https://github.com/search?q=org%3Adotnet%20path%3Asrc%2Farcade%2Feng%2Fcommon%2FREADME.md&type=code. Once we have the fix rolled out, we should make sure to remove all of these

Also one hit in the microsoft org: https://github.com/search?q=org%3Amicrosoft+path%3Asrc%2Farcade%2Feng%2Fcommon%2FREADME.md&type=code

It's possible it also happened for servicing branches right? GitHub search won't find those.

the fix for the bug that caused this has been rolled out, We should now go through the repos that merged these PRs and remove the arcade src/arcade/eng/common

One more which is on AzDO only: https://dev.azure.com/dnceng/internal/_git/dotnet-diagnostictests?path=/src/arcade/eng/common&version=GBmain

So turns out just deleting src/arcade might not be enough, we also need to replace eng/common with a good copy because when the wrong folder was added git recognized some of the files as "moved" there in some repos like wcf.

[akoeplinger]

Found an easier way: trigger the arcade subscription, the new PR will put the files back into eng/common and then you can just delete src/arcade in the PR.
