Add a post_package_info hook to check that all libs listed in system_libs are lower case if host os is Windows

[SpaceIm]

MinGW on Linux doesn't support upper case system libs, but Visual Studio & MinGW on Windows don't care. So the robust approach is to always list system libs full lower case when host os is Windows.

An issue which could be avoided with this hook: conan-io/conan-center-index#15405

@SpaceIm how I can workaround this in my CMakeLists.txt?

You can't, recipe must be fixed.

@rilian-la-te Hi! As @SpaceIm points out, the point of this kind of hooks is to guard against introducing bugs/unexpected issues, so being able to work around them would be counterproductive.
There's the possibility of allowing specific recipes to be ignored by the hooks if the need arises (Which if you check the PRs in this repo, is somewhat common!), but we would need to know why it would be needed :)

@RubenRBS I want to workaround a buggy recipe) For now my best solution is using sed after conan install)
