chore(avm): do not use commit_sparse (#11447)

Experiments in vm1 showed that we are at 90% median column fullness. I'm switching us to use the normal `commit` method which makes sense now that we are using tight polynomials (with virtual size). We could later use `commit` or `commit_sparse` depending on the runtime sparcity of a column (which we know), see: https://github.com/AztecProtocol/aztec-packages/blob/master/barretenberg/cpp/src/barretenberg/vm2/constraining/README.md

For now we use `commit` since the performance is almost the same for our current situation but the memory footprint is lower.
