Upgrade of Ethereum JS to v6 has introduced technical debt

[jeffsmale90]

Various changes to types and member accessibility in Ethereum JS has required changes to Ganache. In #3656, an amount of technical debt was introduced in order to support the merge.

Including, but not limited to:

• any type assertions
• private / protected members accessed from outside of the instance
• weird and convoluted shimming / facade wrapping of level database stuff
• @ts-ignore

Some hacks introduced into our build process:

• 13b6eba
• fd9fe25
• 45d9e39

We should also go through @jeffsmale90's review on #3656 for some tech debt he's found

ethereumjs also introduced a new hashing library that is much slower as a default, so we need to make ejs use our current keccak instead.

We should probably rip out api-extractor and rethink our types approach.

We should discuss removing our alternative lightweight ethereumjs classes and replace them with the expected ethereumjs classes. While we'd likely take a performance hit, the maintenance overhead of keeping them feels like too much.

We have our own block, transactions (transactions and transaction factory), and account classes that we may want to reconsider.

In tags.ts i added the new tags in two different places... and they are in different orders. It's not an actual problem, but it'll drive me crazy.

A little something to track the remaining work:

Problem Description	PR	Status
Implement suggestions in the review of #3656	#3912	Reivew
Fix types building/remove associated hacks (fd9fe25, 45d9e39)	#3913, microsoft/rushstack#3702	Review
Remove webpack hacks 13b6eba	#3916	Review
Replace homemade "lightweight" block class with ejs' block		Another large refactor. It would simplify a lot of conversions to Quantity because we can deal directly with Buffers and Bigints
Replace homemade "lightweight" account class with ejs' account		Moderate effort for little to no reward
Fix ordering of new tags in tags.ts		Merged (well, accidentally pushed directly)
Fix race condition with "does not persist changes to vm or state trie" test	#3825	Merged
Swap out default ejs hashing library	#3820	Merged
Replace homemade "lightweight" transaction class with ejs' transactions		This is a really large refactor. It would remove a lot of code and simplify things, but should probably be a different PR
Simplify/document/improve wrappping of level db	#3880	Merged
Replace homemade "lightweight" address class with ejs' address	#3777	Merged
Remove added any type assertions	#3778	Merged
Remove added instances of accessing private/protected members from outside of instance	#3778	Merged
Remove added @ts-ignores	#3778, #3821	Merged
Open PR with ethereumjs to make DB type more generic		No longer needed. See ethereumjs/ethereumjs-monorepo#2393
