This PR adds a
BlockAccessListBuildertype which will be used to efficiently collect the BAL reads and writes during block execution. After the collection phase we callbuilder.buildBlockAccessList()to return the BAL.Structural validation of block access lists is also implemented which verifies the order of the fields in the BAL and that reads and writes are not present for the same slots as well as checking that the hashed BAL matches an expected hash value.
