Create console project to mimic UI

In order to support integration on build servers, it would be nice to have a new project that takes build configuration from command line and outputs the trace file.

It needs, at the bare minimum:

* Path to solution to build: i.e. `C:\path\to\solution.sln`.
* Configuration: i.e. `Debug`.
* Platform: i.e. `x64`.
* Target: i.e. `Rebuild`.
* Output trace file: i.e. `C:\path\to\trace.json`.

Ideas for execution with different formats (second one resembles MSBuild a bit more):
`builder_console.exe C:\path\to\solution.sln -o C:\path\to\trace.json -c Debug -p x64 -t Rebuild`
`builder_console.exe C:\path\to\solution.sln /o:C:\path\to\trace.json /c:Debug /p:x64 /t:Rebuild`

It would also be interesting to be able to provide:

* Use `/Bt+` flag.
* Use `/time+` flag.
* Keep intermediate `Events.json` file.

Start by reviewing the existing UI flow that builds a solution and produces the trace file. Define the console project's command-line inputs for solution path, configuration, platform, target, and output path, then verify that it can produce the same trace output for a build-server invocation. Treat /Bt+, /time+, and retaining Events.json as additional scope.
