x86/resctrl: Split trace.h
trace.h contains all the tracepoints. After the move to /fs/resctrl, some
of these will be left behind. All the pseudo_lock tracepoints remain part
of the architecture. The lone tracepoint in monitor.c moves to /fs/resctrl.
Split trace.h so that each C file includes a different trace header file.
This means the trace header files are not modified when they are moved.
