Update expect.txt keywords and csproj package references

Updated `expect.txt` to modify or replace specific keywords for
consistency. Added `System.CodeDom` and `System.Diagnostics.
EventLog` package references to `PowerDisplay.Lib.UnitTests.csproj`
with `ExcludeAssets` set to `runtime` to prevent conflicts with
.NET SDK-provided DLLs.
