Optimize xTaskIncrementTick for configNUMBER_OF_CORES > 1 (#1118)

Optimize xTaskIncrementTick for configNUMBER_OF_CORES > 1 (#1118)

The original implementation only initializes the first
variable. After executing xTaskIncrementTick, the schedule
might not behave as expected.

When configUSE_PREEMPTION == 1 & configUSE_TIME_SLICING == 1,
replace setting xYieldRequiredForCore[ xCoreID ] with setting
xYieldPendings[ xCoreID ].

And when configUSE_PREEMPTION == 1, simplify the check
condition to only check xYieldPendings[ xCoreID ].
