185f880e78 NetworkParameters: Move genesis block construction to lazy getter 
This refactoring breaks the cyclic dependency of NetworkParameters constructors
on the constructors in Block and will allow us to migrate the code
now in the getGenesisBlock() methods into (atomic) factories/constructors
in `Block` allowing us to create block objects that are unmodifiable/immutable.

787c9caced Block, AbstractBitcoinNetParams subclasses: Constants 
* Add Block.STANDARD_MAX_DIFFICULTY_TARGET and use in subclasses
* Always define maxTarget in terms of a nBits constant and use
  Utils.decodeCompactBits()
* Define constants for GENESIS_TIME and GENESIS_NONCE

9fa36d495f UnitTestParams: Set UnitTest maxTarget to EASIEST_DIFFICULTY_TARGET 
The tests are currently using a custom value for maxTarget
that can’t be generated via CompactBits format.

This commit changes the string constant to match what would be
generated by using Utils.decodeCompactBits(EASIEST_DIFFICULTY_TARGET).

42bb5b386e AbstractBitcoinNetParams subclasses: Improve Genesis hash checking 
1. Define Sha256 constants for expected hashes
2. Compare hashes in binary form
3. Move hash comparison to immediately follow Block creation
4. Add error message to the check state call

0cb686481f Block: Fix JavaDoc comment on EASIEST_DIFFICULTY_TARGET 
It said “half of all possible hash solutions” which
led me to believe that decodeCompactBits() would
extend 1’s all the way out to the least significant
bit.

a19986d475 RegTestParams: remove redundant init of genesis block 
(It looks like the override of getGenesisBlock() was added
back in 2013 when RegTestParams was a subclass of
TestNet2Params.)

eb74d8aae4 Reorganize NetworkParameters subclass for easy diffs 
Reorganize the initialization of the constants in each NetworkParameters
subclass so we can easily do diffs of `MainNetParms` vs `TestNet3Params`
and easily see how they are the same and how they are different.

I also reorganized the import statements so they “diff” better as well.

Other than those changes the only code I actually changed is
using the constant `PAYMENT_PROTOCOL_ID_UNIT_TESTS` instead of “unittest”
in getPaymentProcolId in UnitTestParams.

This will help us with the next step which is to create symbolic constants
for some of the parameters for the genesis blocks.

c31d071a04 Block: Move NetworkParameters::createGenesis to Block 
Its a factory method for creating Blocks, so it really belongs
there. Moving it there will also help us move further along
our path to reduced mutability in the Block class.

a29aa8df5c Github Actions: Use ‘temurin’ JDK 8 + 11 
Temurin is the Eclipse Foundation’s successor to AdoptOpenJDK
and is likely to continue to be the most widely-used community
distribution.

Unfortunately, Temurin only provides JDK 8, 11, and 16,
and since bitcoinj can’t yet be built with JDK 16, we’ll
drop the JDK 15 build without replacing it with JDK 16.
