Use a strongly typed LogicalDisplayId for displayId(2/n)

Currently, we use int32_t for displayId, which is not a safe type, and
it may also lead to misdefinition of types. Here, we introduce
LogicalDisplayId as a strong type for displayId and move all contents
of constants.h into LogicalDisplayId.h.
