Increase contracts bench stability

[ggwpez]

The FRAME benchmarking does not handle the case well where a linear component as only a range of [0, =1] since in this case it has to calculate a linear formula from just two points which is unstable.

Now bumping these upper limits back API_BENCHMARK_BATCHES should improve stability. There are some more benches which could profit from this, but let's first see if we go into the right direction by re-benching.

This partially reverts #12526

Looks much better now (SWC link). Note that it is using the Asymptotic mode to mostly ignore the base-weight, since for the contracts it does not really matter.

On Exact-worst it shows the ones which have increase base-weight; as said, should not matter here.
