Ninja: Provide a way to clean a specific target

I made a change to the sources of an example but couldn't see any changes when running it after building, so I figured I'd try to rebuild the example (object files, executable, etc.) completely. I searched for "clean target ninja" and found this comment:

https://github.com/ninja-build/ninja/issues/317#issuecomment-5948119

Not knowing any better, I tried it out:

C:\dev\qt-dev-debug\qtdeclarative>ninja -t clean quick_shadereffects
Cleaning... 2958 files.

Turns out this actually removes not only the build files for the specific target, but also all of its dependencies.

I asked around a bit internally and was told that I could do the following:

ninja -t clean -r CXX_COMPILER__quick_shadereffects_Debug
ninja -t clean -r CXX_STATIC_LIBRARY_LINKER__quick_shadereffects_Debug

Apparently this cleans files specific to a rule and target, but I don't really understand how it works and doubt I would remember what to type. I was recommended to do the following instead:

rm -fr path\to\build\dir
cmake .
ninja

It would be nice if there was a convenient way to rebuild a specific target, or at least clean the artifact object files and link artifact.
