fix: Add MPU wrapper for xTimerDelete API (#1412)

Browse source 
When using MPU wrappers v2, xTimerDelete needs to be a real function
rather than a macro so that the kernel object pool index can be freed
after the timer is successfully deleted. Without this, deleting a timer
leaks the kernel object pool entry.
