Fix PcdTimerPeriod from 100,000 to 10,000. Since the unit base of PcdTimerPeriod is 100ns.
100,000 * 100ns = 10ms (interval of hardware timer interrupt) 10,1000 * 100ns = 1ms (interval of hardware timer interrupt) In GRUB, the required timer granularity is only 1ms. If interval of hardware timer interrupt is 10ms in UEFI, GRUB will only get all timer granularity >= 10ms. At least, the timeout of boot menu in GRUB is much slower. Only the interval of hardware timer interrupt is 1ms in UEFI, the timeout of boot menu in GRUB works well.
