cmake: add target property dumper helper function

Browse Source 
It's pretty rough and a giant hack, but helps debugging and findind ways
while navigating the CMake maze. I find it sad CMake doesn't have
a built-in function for this that works correctly in all situations.
It's invaluable to be able to see what properties and values an object
has.

It's also possible there is a better solution to this, but I could not
find it.

Cherry-picked from #16973

Closes #17701
