Make naming of tupdesc related structs more consistent with the rest of PG.
We usually don't change the name of structs between the struct name itself and the name of the typedef. Additionally, structs that are usually used via a typedef that hides being a pointer, are commonly suffixed Data. Change tupdesc code to follow those convention. This is triggered by a future patch that intends to forward declare TupleDescData in another header - keeping with the naming scheme makes that easier to understand.
