[Product] Add support for configuring withdrawals

[Wodann]

Internally, EDR's block builder supports the inclusion of withdrawals, post-Shanghai hardfork. However, we don't expose a means for the user of the mining functions nor provider to specify the withdrawals.

Currently, we always use an empty set of withdrawals for locally mined post-Shanghai blocks.

We should discuss a product need and design for including configuring withdrawals for a mined block. The design should take into consideration that not all chain types process withdrawals. E.g. OP should not receive withdrawals, whereas L1 Ethereum should.

Definition of done

• Come up with a product design for configuring the withdrawals of a block (if deemed necessary)
• (If deemed necessary) implement the product design
• Remove TODO references to this issue
