MdeModulePkg/Core: fix bits operation error on a boundary condition
If given address is on 64K boundary and the requested bit number is 64, all SetBits(), ClearBits() and GetBits() will encounter ASSERT problem in trying to do a 64 bits of shift, which is not allowed by LShift() and RShift(). This patch tries to fix this issue by turning bits operation into whole integer operation in such situation.
