[Feature] Remove Empty Scalars Marker

Describe the feature you would like

In op-rs/maili#45, the Ecotone L1 block info was amended to contain empty scalars marker bool for revm. Since scalars will always be empty in the first ecotone block, we may be able to remove the empty_scalars bool entirely and check if both the base_fee_scalar and blob_base_fee_scalar are zero.

This is what revm does when constructing the l1 block info from the db - the bool just acts as a helper. We should just be able to create a method on the L1BlockInfoEcotone that returns if both blob_base_fee_scalar and base_fee_scalar are zero.

@refcell I have created a PR that is more or less what you had in op-rs/maili#54

Based on the info provided and comms you guys have had in the PR thread, these diffs appear to be sufficient. Are there any other diffs or tests you think are required for this PR?

TY!
