feat: optimism-specific receipt

[klkvr]

Closes #12588

Same as #13295 but for OP receipt

[emhane]

is it not possible to make an enum with one variant wrapping op_alloy_consensus::OpDepositReceipt?

[klkvr]

this would require a manual compact impl through a struct same as the current one for compatibility but should be possible

[klkvr]

@emhane I've created a draft using an enum #13334, it needs an op-alloy release

I think we can proceed with the current approach given that it won't require any changes to existing OP components, and can refactor this into an enum and integrate everywhere later

[mattsse]

lgtm pending op-alloy bump

[mattsse]

released now

[mattsse]

this could be a footgun.

perhaps a better approach long term would be a trait, maybe.

[klkvr]

I've looked into this, we can't solve this with a trait while we depend on modular_bitifield the get_bit_size output is translates into B2/B1 etc inputs for bitfield macro:

#[bitfield]
pub struct OpReceiptFlags {
    pub tx_type_len: B2,
    pub success_len: B1,
    pub cumulative_gas_used_len: B4,
    pub deposit_nonce_len: B1,
    pub deposit_receipt_version_len: B1,
    pub __zstd: B1,
    #[skip]
    unused: B6,
}
