Regression since 3.93 caused by 752c6d668b.
Follow the code from 2.93 which was always leaving curve modifiers
evaluation with a valid and clean state of the bounding box.
This is also what was proposed and agreed on in the following
design task: T92206: Bounding Box: compute during depsgraph evaluation
Tested with files from T90808 and T93384.
For the 3.0 going with the safest and minimal change. The rest of
the bounding box un-entanglement is to happen outside of the stable
branch.
Thanks The patch is based on the code from Philipp Oeser and
investigation by Germano Cavalcante and Dr. Sybren A. Stüvel,
thanks!
