Everywhere: Move all host tools into the Lagom/Tools subdirectory
This allows us to remove all the add_subdirectory calls from the top level CMakeLists.txt that referred to targets linking LagomCore. Segregating the host tools and Serenity targets helps us get to a place where the main Serenity build can simply use a CMake toolchain file rather than swapping all the compiler/sysroot variables after building host libraries and tools.
