Rationalize handling of VacuumParams
This commit refactors the vacuum routines that rely on VacuumParams,
adding const markers where necessary to force a new policy in the code.
This structure should not use a pointer as it may be used across
multiple relations, and its contents should never be updated.
vacuum_rel() stands as an exception as it touches the "index_cleanup"
and "truncate" options.
VacuumParams has been introduced in 0d831389749a, and 661643dedad9 has
fixed a bug impacting VACUUM operating on multiple relations. The
changes done in tableam.h break ABI compatibility, so this commit can
only happen on HEAD.
