Update system time (#192)

* [sdk] use gtimer for system time

* Use gtimer instead of freertos time as freertos only covers until 32-bits, but matter requires 64-bits

* [sdk] fix build issue with af.h

* Fix build issue with af.h as header has been removed and declaration is moved to attribute-table.h

* [sdk] change timer used for system time

* Change TIMER4 to TIMER5 as TIMER4 is already used in rtc_init(). To prevent conflict, change to TIMER5.
