Fix Platform static initialization interdependencies w/ GlueGen native library loading

Some Platform field declarations and it's static initialization has been delegated
to it's new abstract super class PlatformPropsImpl to solve
static initialization interdependencies w/ the GlueGen native library loading
and it's derived information {@link #getMachineDescription()}, {@link #is32Bit()}, ..<br>

This mechanism is preferred in this case to avoid synchronization and locking
and allow better performance accessing the mentioned fields/methods.
