Subject: Introduce IndexAM fields for parallel vacuum.

Introduce new fields amusemaintenanceworkmem and amparallelvacuumoptions
in IndexAmRoutine for parallel vacuum.  The amusemaintenanceworkmem tells
whether a particular IndexAM uses maintenance_work_mem or not.  This will
help in controlling the memory used by individual workers as otherwise,
each worker can consume memory equal to maintenance_work_mem.  The
amparallelvacuumoptions tell whether a particular IndexAM participates in
a parallel vacuum and if so in which phase (bulkdelete, vacuumcleanup) of
vacuum.
