cmake: use ALLOW_MEMORY_GROWTH=1 for web examples The default memory limit for emscripten applications is 16 mergabytes, which might be to little for some examples, especially given that the resources are also included in that limit.

CMake: Major cleanup to support find_package(raylib) Remove that link_libraries_to_executable() hack and defines a proper raylib target that can be used with target_link_libraries. The same target is also available for external (user) code by using find_package(raylib). This results in: - Remove hardcoded build directories from examples and games CMakeLists.txt - Allow rlgl_standalone and other special examples to be built easily - Allow CMake projects to find_package(raylib instead of fiddling with pkg-config - Makes code a little more maintainable - Fixes #471, #606. - Makes code less confusing by removing the double use of PLATFORM (#584). Note that this is still not _The Right Way_(TM), because normally raylib-config.cmake (or its includes) would be automatically generated. I didn't manage to get that to work though, so I went the easier route of just wrapping pkg_check_modules for consumption by find_package.
