Kernel: Move x86-specific timer code handling to Arch/x86/Time directory

The APICTimer, HPET and RTC (the RTC timer is in the context of the PC
RTC here) are timers that exist only in x86 platforms, therefore, we
move the handling code and the initialization code to the Arch/x86/Time
directory. Other related code patterns in the TimeManagement singleton
and in the Random.cpp file are guarded with #ifdef to ensure they are
only compiled for x86 builds.
