[wix-devs] RuntimeTest in wix4

[Bob Arnson]

While doing some work in the wix4 tests -- https://github.com/wixtoolset/wix4/pull/224 -- I ran across something I found an oddity.

A bunch of WiX and Burn tests are marked with the RuntimeTest attribute, which means they muck with the machine (and usually require elevation). I'm thinking the best way to organize them is by putting them into their own assemblies rather than requiring a magic environment variable to be set while running all the other tests.

Maybe there's some history but I can't imagine why different assemblies are a bad idea. Any thoughts/objections?
