CI: build before analysis to support C++ Modules (#325)

The code analysis action needs .ddi and .modmap files that CMake
generates during the build phase (dependency scanning).  Without
a build step, the action cannot determine module dependencies or
pass the correct -interface/-ifcOutput/-reference flags to cl.exe.

Add a build step between configure and analysis.
