With this, we get rid of platform specific timer interfaces. The new Timer class does the same as the old Clock class and has a generic interface. The old Timer class was merely used by the old Clock class. Also, we get rid of having only one timer instance which we tell with each method call for which CPU it shall be done. Instead now each Cpu object has its own Timer member that knows the CPU it works for. Also, rename all "tics" to "ticks". Fixes #2347
