[Nakamoto] stacks-signer needs to track its transactions to verify a block contains these special cased transactions

[jferrant]

Stacks signer must be able to validate the contents of a block to verify that it contains the control plane transactions it expects.

Add local state for signers to track expected transactions and verify that a proposed block contains them. Note that once this block is appended, the signer must be able to clear them from the queue to prevent denial of subsequent blocks that of course will not contain them.

Depends on #3930
