Enforce cube dimension limit in all cube construction functions
contrib/cube has a limit to 100 dimensions for cube datatype. However, it's
not enforced everywhere, and one can actually construct cube with more than
100 dimensions having then trouble with dump/restore. This commit add checks
for dimensions limit in all functions responsible for cube construction.
Backpatch to all supported versions.
