Standardize one aspect of rmgr desc output.

Browse Source 
Bring heap and hash rmgr desc output in line with nbtree and GiST desc
output by using the name latestRemovedXid for all fields that output the
contents of the latestRemovedXid field from the WAL record's C struct
(stop using local variants).

This seems like a clear improvement because latestRemovedXid is a symbol
name that already appears across many different source files, and so is
probably much more recognizable.
