Cmake package config files all wrong

[Fleischner]

Do not allow Package Config Files (*.pc).
They are all wrong! (Assimp, ccd, fcl, flann, freeglut, glew, tinyxml2, and i assume many more)
And indistinguishable between release and debug.

There should be either:

1. an rule checker to prevent having these files
2. require them in a certain location and check the content
3. require them in a certain location and create them with a fixed pattern by vcpkg

Since #9861 merged, the only thing we need to do is to fix these ports.

@Fleischner Could you provide me a list whose ports have this problem?

Related: #6045.

@Fleischner ,What are the ports in the latest library that still have these problems? can you give a list

Now I think we can close this issue, since we have vcpkg_fixup_pkgconfig, this issue has been fixed.
