sched/headers: ARM needs asm/paravirt_api_clock.h too

Add <asm/paravirt_api_clock.h> for arch/arm/, mapped to <asm/paravirt.h>,
to simplify #ifdeffery in generic code.

Fixes this build error introduced by the scheduler tree:

  In file included from ../kernel/sched/core.c:81:
  ../kernel/sched/sched.h:87:11: fatal error: asm/paravirt_api_clock.h: No such file or directory
     87 | # include <asm/paravirt_api_clock.h>
