Mark ItemPointer arguments as const in tuple/table lock functions

The functions LockTuple, ConditionalLockTuple, UnlockTuple, and
XactLockTableWait take an ItemPointer argument that they do not
modify, so the argument can be const-qualified to better convey intent
and allow the compiler to enforce immutability.
