find_program: Correctly use scripts found in PATH

We also need to check whether the program found in PATH can be executed
directly by Windows or if we need to figure out what the interpreter is
and add it to the list.

Also add `msc` to the list of extensions that can be executed natively

Includes a project test and a unit test for this and all expected
behaviours on Windows.
