New code layout - breaking change in cpu_features_macros.h (#194)

Browse Source 
This commit helps with platform code separation (fixes #3). It should also help with the build as we can simply include all `impl_*.c` files regardless of OS / arch.

Note: this patch contains breaking changes in `include/cpu_features_macros.h`
 - `CPU_FEATURES_OS_LINUX_OR_ANDROID` does not exist anymore
 - `CPU_FEATURES_OS_FREEBSD`, `CPU_FEATURES_OS_ANDROID` and `CPU_FEATURES_OS_LINUX` are now mutually exclusive (i.e. `CPU_FEATURES_OS_ANDROID` does not imply `CPU_FEATURES_OS_LINUX`)
 - `CPU_FEATURES_OS_DARWIN` has been renamed into `CPU_FEATURES_OS_MACOS` to be able to target non-Mac Apple products (IOS, TV, WATCH). They are now targetable with `CPU_FEATURES_OS_IPHONE`. This matches Apple naming convention described in [this stackoverflow](https://stackoverflow.com/a/49560690).
