Eliminate a few HnswPtrAccess invocations
...
HnswPtrAccess() is pretty cheap, but it stills seems worthwhile to
avoid repeated calls in the hot paths when it can be easily avoided.

Remove offsethash
...
The original motivation was to eliminate the superfluous HnswPtrAccess
call from AddToVisited. The caller has to call HnswPtrAccess() anyway,
so it makes sense to pass the HnswElement rather than HnswElementPtr
to AddToVisited(). But then I realized that we can use the
pointer-variant even with shared memory, because the visited-hash is
backend-private, and the addresses where the elements are mapped to in
shared memory are stable within the backend.

Add direct include to pairingheap.h in headers
...
ivfflat.h and hnsw.h have references to pairingheap_node, so they need
to include lib/pairingheap.h. It happened to work, because
lib/pairingheap.h was being included indirectly through
nodes/execnodes.h, but let's be explicit.
Remove the include from hnswbuild.c, because there are no calls to
pairingheap functions in that file. Instead, add the includes to
hnswutils.c and ivfscan.c, which do have such calls. They are not
strictly necessary again because of the indirect include from hnsw.h
and ivfflat.h, but let's be explicit while we're messing with this.
