bufmgr: Change BufferDesc.state to be a 64-bit atomic This is motivated by wanting to merge buffer content locks into BufferDesc.state in a future commit, rather than having a separate lwlock (see commit c75ebc657ff for more details). As this change is rather mechanical, it seems to make sense to split it out into a separate commit, for easier review.
