Previously, we had code inside the stage builder to enforce
that only a single transition was allowed per-statement phase.
This would have made it hard to implement CREATE statements
since we need to apply multiple transitions. To address this,
this patch adds dep rules to limit the number of transitions,
which will be later disabled for create statements. To help
support this a new precedence type is introduced.

Previously, the two version invariant was enforced
for all non-dropped descriptors. When creating new
descriptors if they are going to be decomposed into
individual elements, then similar logic needs to
skip added descriptors. To address this, this patch
disables these rules for added descriptors.
