Get number of cycles.

AIE-ML has a Tile counter which is a free running counter. This intrinsic returns the 64 bit tile counter value. In order to measure the number of cycles taken by a piece of code, this intrinsic should be read first at the start and again at the end of a code section. The difference is the number of cycles consumed by the code section @ AIE-ML Clock frequency.
