GA aka.ms links should point to blob storage

[michellemcdaniel]

After we publish to the stable blob storage locations, we should take that information, and point the GA aka.ms links at those blob storage locations. This would allow us to fix #7240 and #7239 without affecting the release.json file, and wouldn't require us to publish anything we don't want to

I've written up some code that will create the mapping from the new dotnetcli location (ie, where repo propagation will move them to) and the aka.ms links those changes will correspond to. It spits out a json file that UpdateAkaMsLinks can read. I update UpdateAkaMsLinks to allow the specifying of a file that doesn't require any changes to it (right now, various bits are prepended to the file name to get the "final" version).

What's left to do:

• Remove the original support that I added for GA. We don't want the links pointing to the visualstudio location at all.
• Add tests for the changes in ReleaseCli
• Add running of the tool to the staging pipeline, and have it dump the file on vsufile.
• Add an additional running of UpdateAkaMsLinks to the release/RM pipeline for 5.0+.

The main part of this has been checked in and needs to be rolled out.

The part to turn on the actual creation of the links will need to be added to the RM/release pipelines

Opened a new issue for the final piece: #7318. Closing this again.
