Visual Studio ninja not found

### Brief Issue Summary

With Visual Studio 2022 and its CMake support installed, vscode-cmake-tools does find the `cmake.exe` that it installs. It does not, however, find Ninja. If vscode-cmake-tools is able to find Visual Studio's `cmake.exe`, it seems like it ought to be able to locate its `ninja.exe`, as well.

### CMake Tools Diagnostics

Start by reproducing the issue with the attached vscode-cmake-tools-test.zip using Visual Studio 2022 and its CMake support. Trace the Visual Studio discovery path that finds cmake.exe and determine why ninja.exe is not located; done means the same setup finds Visual Studio's Ninja executable.
