Revise sinval code to remove no-longer-used tuple TID from inval messages.

Revise sinval code to remove no-longer-used tuple TID from inval messages.

This requires adjusting the API for syscache callback functions: they now
get a hash value, not a TID, to identify the target tuple. Most of them
weren't paying any attention to that argument anyway, but plancache did
require a small amount of fixing.

Also, improve performance a trifle by avoiding sending duplicate inval
messages when a heap_update isn't changing the catcache lookup columns.
