Implement the new block subsidy function (#1830)
* Replace the old blockSubsidy parameters with the new ones.

* Return subsidyGenesisReward if blockHash is the genesis hash.

* Traverse a block's past for the subsidy calculation.

* Partially implement SubsidyStore.

* Refer to SubsidyStore from CoinbaseManager.

* Wrap calcBlockSubsidy in getBlockSubsidy, which first checks the database.

* Fix finalityStore not calling GenerateShardingID.

* Implement calculateAveragePastSubsidy.

* Implement calculateMergeSetSubsidySum.

* Implement calculateSubsidyRandomVariable.

* Implement calcBlockSubsidy.

* Add a TODO about floats.

* Update the calcBlockSubsidy TODO.

* Use binary.LittleEndian in calculateSubsidyRandomVariable.

* Fix bad range in calculateSubsidyRandomVariable.

* Replace float64 with big.Rat everywhere except for subsidyRandomVariable.

* Fix a nil dereference.

* Use a random walk to approximate the normal distribution.

* In order to avoid unsupported fractional results from powInt64, flip the numerator and the denominator manually.

* Set standardDeviation to 0.25, MaxSompi to 10_000_000_000 * SompiPerKaspa and defaultSubsidyGenesisReward to 1_000.

* Set the standard deviation to 0.2.

* Use a binomial distribution instead of trying to estimate the normal distribution.

* Change some values around.

* Clamp the block subsidy.

* Remove the fake duplicate constants in the util package.

* Reduce MaxSompi to only 100m Kaspa to avoid hitting the uint64 ceiling.

* Lower MaxSompi further to avoid new and exciting ways for the uint64 ceiling to be hit.

* Remove debug logs.

* Fix a couple of failing tests.

* Fix TestBlockWindow.

* Fix limitTransactionCount sometimes crashing on index-out-of-bounds.

* In TrustedDataDataDAABlock, replace BlockHeader with DomainBlock

* In calculateAveragePastSubsidy, use blockWindow instead of doing a BFS manually.

* Remove the reference to DAGTopologyManager in coinbaseManager.

* Add subsidy to the coinbase payload.

* Get rid of the subsidy store and extract subsidies out of coinbase transactions.

* Keep a blockWindow amount of blocks under the virtual for IBD purposes.

* Manually remove the virtual genesis from the merge set.

* Fix simnet genesis.

* Fix TestPruning.

* Fix TestCheckBlockIsNotPruned.

* Fix TestBlockWindow.

* Fix TestCalculateSignatureHashSchnorr.

* Fix TestCalculateSignatureHashECDSA.

* Fix serializing the wrong value into the coinbase payload.

* Rename coinbaseOutputForBlueBlock to coinbaseOutputAndSubsidyForBlueBlock.

* Add a TODO about optimizing trusted data DAA window blocks.

* Expand on a comment in TestCheckBlockIsNotPruned.

* In calcBlockSubsidy, divide the big.Int numerator by the big.Int denominator instead of converting to float64.

* Clarify a comment.

* Rename SubsidyMinGenesisReward to MinSubsidy.

* Properly handle trusted data blocks in calculateMergeSetSubsidySum.

* Use the first two bytes of the selected parent's hash for randomness instead of math/rand.

* Restore maxSompi to what it used to be.

* Fix TestPruning.

* Fix TestAmountCreation.

* Fix TestBlockWindow.

* Fix TestAmountUnitConversions.

* Increase the timeout in many-tips to 30 minutes.

* Check coinbase subsidy for every block

* Re-rename functions

* Use shift instead of powInt64 to determine subsidyRandom
