Moved the MdePkg to OldMdePkg so that new code in MdePkg does not break existing builds. Also updated the SPD and FPD files UiNames

- This function computes the bit position of the highest bit set in the 64-bit

- Otherwise, a value between 0 and 63 is returned.

- @param Operand The 64-bit operand to evaluate.

- @return Position of the highest bit set in Operand if found.
