Enable extra warnings in Source CMakeLists, not in root CMakeLists
Having extra warnings enabled for everything including external
libraries produces an overwhelming amount of warnings in code that
isn't even part of our codebase.

Move the various warning flags to Source/CMakeLists.txt to get rid
of those useless warnings.

Note that the Source CMakeLists.txt is already where the MSVC warnings
are defined, so this commit improves consistency as well.
