+ Produces the Metronome Architectural Protocol on top of Timer Library.\r
\r
This is a generic implementation of the Metronome Architectural Protocol that\r
layers on top of an instance of the Timer Library. The Timer Library provides\r
overflows that could occur for long delays if only nanoseconds were used and also\r
provides the greatest accuracy for small delays. \r

+ This function implements EFI_METRONOME_ARCH_PROTOCOL.WaitForTick().\r
The WaitForTick() function waits for the number of ticks specified by \r
TickNumber from a known time source in the platform. If TickNumber of \r
ticks are detected, then EFI_SUCCESS is returned. The actual time passed \r
