vacuumlazy.c: Standardize rel_pages terminology.
VACUUM's rel_pages field indicates the size of the target heap rel just
after the table_relation_vacuum() operation began. There are specific
expectations around how rel_pages can be related to other nearby state.
In particular, the range of rel_pages must contain every tuple in the
relation whose tuple headers might contain an XID < OldestXmin.
Consistently refer to the field as rel_pages to make this clearer and
more discoverable.
This is follow-up work to commit 73f6ec3d from earlier today.
