Proto,tests: Check operation size limit by default

Context

The development of Transaction Rollups has proven that sometimes, it is mandatory to check that the arguments of a layer-1 operations actually fit in a Tezos operation.

This patchset sets the check_size optional argument of Incremental.add_operation to true by default, and add a similar argument to Block.bake.

Manually testing the MR

CI shall prevail. It will be interesting to see which tests start failing.
