[formcalc] Consider width along with depth of tree
When building the formcalc parser trees we need to limit on width along
with depth. It's possible to generate a tree of a single depth but is
more then 20k nodes wide. This will eventuall cause stack overflow
issues.
This CL re-uses the depth check for the grammar expressions in which
we're extending the width of the tree we count that against our depth
check.
