[tests] Remove net472 multitargeting (#7932)

We are no longer running the `net472` versions of our desktop tests,
and we can save a bit of time by not building them either.

I've removed the `net472` version of `xaprepare` as well, as we have
a hard dependency on .NET 7+.

The `run-msbuild-device-tests.yaml` template was unused and is removed.
