Refactor MSVC workspace #632
Description
The MSVC workspace has long suffered from broken code browsing on the embedded targets. Intellisense can't find the symbols for the solution configurations of the target project.
It might be best to eliminate the project target and keep only the ref_app. In doing so, each solution configuration (each of the many embedded target boards) can be made a solution configuration of ref_app.
This is expected to simplify the MSVC solution and also make individual code browsing work for all sources in each configuration.
