This removes the block template generation code related to prioritization of low-fee/free transactions. The following is an overview of the changes: - Remove logic to select sort method based on the block priority size from block template generation - Remove now unused mining.MinHighPriority constant - Remove now unused mining.Policy.BlockPrioritySize field - Remove now unused txPQByStakeAndFeeAndThenPriority func - Remove tests related to txPQByStakeAndFeeAndThenPriority
