MSBUILDDEBUGENGINE should infer maximal logging (MSBUILDLOGTASKINPUTS)

[rainersigwald]

I was debugging using the magic MSBUILDDEBUGENGINE for dotnet/roslyn#62314 when I noticed that task inputs weren't in the resultant binlog.

The binary logger sets some internal environment variables to make sure it logs everything, but only when attached through "the usual ways", and they don't all get triggered via MSBUILDDEBUGENGINE but they should.

The only one I know of for sure is MSBUILDLOGTASKINPUTS but we should check for others.
