Add support for net7.0 to dotnet.py script

[kunalspathak]

Currently, when we do dotnet.py install --architecture x64 --install-dir D:\workspace\_work\1\s\workitem\performance\tools\dotnet\x64 --verbose , it installs net6.0 but it should start installing net7.0

Good call. We need to spin up a release/6.0.1xx branch in the perf repo before we can change this. Is this blocking you?

Yes...superpmi collection is failing with following errors:

Working on a fix for this now.

These three PRs should get us in a good place, but the runtime ones will have to go in first.
