Move ALTER ... ALL IN to ProcessUtilitySlow

Now that ALTER TABLE .. ALL IN TABLESPACE has replaced the previous
ALTER TABLESPACE approach, it makes sense to move the calls down in
to ProcessUtilitySlow where the rest of ALTER TABLE is handled.

This also means that event triggers will support ALTER TABLE .. ALL
(which was the impetus for the original change, though it has other
good qualities also).

Back-patch to 9.4 as the original rework was.
