This implements the conversion of existing blob transactions to the new proof
version. Conversion is triggered at the Osaka fork boundary. The conversion is
designed to be idempotent, and may be triggered multiple times in case of a reorg
around the fork boundary.
This change is the last missing piece that completes our strategy for the blobpool
conversion. After the Osaka fork,
- new transactions will be converted on-the-fly upon entry to the pool
- reorged transactions will be converted while being reinjected
- (this change) existing transactions will be converted in the background

This is an alternative to #31309
With eth/68, transaction announcement must have transaction type and
size. So in announceTransactions, we need to query the transaction from
transaction pool with its hash. This creates overhead in case of blob
transaction which needs to load data from billy and RLP decode. This
commit creates a lightweight lookup from transaction hash to transaction
size and a function GetMetadata to query transaction type and
transaction size given the transaction hash.
