Added a couple of new/updated test/debug Visual Studio utility projects.
These projects can be used to quicker get up to speed when there is a need
to run/test/debug mono runtime tests inside Visual Studio debugger.
Added utility projects can be used to run mini regression tests using JIT as
well as compile/run full AOT:ed versions of mini regression tests or other assemblies.
The different .prop files are also organized so they can be reused when adding additional
run/test/debug projects going forward.
