Add `scroll_` namespace endpoint

[greged93]

Describe the feature

Add the following scroll endpoints:

• scroll_getL1SyncHeight
• scroll_getL1MessageByIndex
• scroll_getFirstQueueIndexNotInL2Block
• scroll_getFirstQueueIndexNotInL2Block
• scroll_getNumSkippedTransactions
• scroll_syncStatus
• scroll_estimateL1DataFee
• scroll_getSkippedTransaction
• scroll_getSkippedTransactionHashes

The majority of these RPCs are not needed and should not be added to Reth.

I think we should add scroll_getL1MessageByIndex and scroll_estimateL1DataFee, and consider scroll_syncStatus with a reasonable spec (does not need to match l2geth).
