Update structs for processing public function data in rollup circuits

[spalladino]

Changes related to processing public function data in rollup circuits, instead of in public kernel circuit.

• Add missing public data tree fields to root rollup public inputs
• Set public data tree start and end roots in merge and root circuits
• Update base rollup inputs and public kernel circuit inputs and outputs
• Update public data tree in circuit block builder and not in public tx processor
• Verify state reads in base rollup circuit
• Process state transitions in base rollup circuit
• Include new fields in root rollup calldata hash (see Root Rollup Public Input Hash #353 and Update rollup contract to incorporate public data in state hashing #272 )
