This adds support for the "yParity" field in transaction objects returned by RPC
APIs. We somehow forgot to add this field even though it has been in the spec for
a long time.

This change rearranges the accessor methods in block.go and fixes some minor issues with
the copy-on-write logic of block data. Fixed issues:

- Block.WithWithdrawals did not create a shallow copy of the block.

- Block.WithBody copied the header unnecessarily, and did not preserve withdrawals.

However, the bugs did not affect any code in go-ethereum because blocks are *always*
created using NewBlockWithHeader().WithBody().WithWithdrawals()

Sets the `currentExcessBlobGas` from env, alternatively calculates it based on `parentExcessBlobGas` and `parentBlobGasUsed`. It then emits the `currentExcessBlobGas` and `currentBlobGasUsed` into the output, to be used as parent-values for a future iteration.

This is a spin-out from the EIP-4844 devnet branch, containing just the Engine API modifications
and nothing else. The newPayloadV3 endpoint won't really work in this version, but we need the
data structures for testing so I'd like to get this in early.

This change removes PoW header syncing related code from LES and also deletes 
duplicated packages les/catalyst, les/downloader and les/fetcher. These package copies
were created because people wanted to make changes in their eth/ counterparts, but weren't
able to adapt LES code to the API changes.
