Follow current BaseFee approach

zkevm-circuits/zkevm-circuits/src/table/block_table.rs

Lines 19 to 20 in 443da4b

    
           /// Base Fee field 
        
           BaseFee = 8,

We need to define new field BlobBaseFee in blocktable, with new opcode BLOBBASEFEE to lookup blocktable and retrieve the value

Implementation reference for lookup in block table https://github.com/privacy-scaling-explorations/zkevm-circuits/blob/main/zkevm-circuits/src/evm_circuit/execution/block_ctx.rs#L29
