Fix 2 BootScript thunk issue on MEM_POLL.
1) MEM_POLL stall time is incorrect.
Framework version: Duration is used for Stall(), which is Microseconds.
Total time is: Duration(Microseconds) * LoopTimes.
PI version: Duration is always 100ns. Delay is LoopTimes.
Total time is: 100ns * Delay.
So Delay = Duration(Microseconds) * LoopTimes / 100ns
= Duration * 1000ns * LoopTimes / 100ns
= Duration * 10 * LoopTimes
2) MEM_POLL BitMask/BitValue order is incorrect.
Framework version: First BitMask, then BitValue
PI version: First Data, then DataMask
So we revert their order in function call
