validation: detect and verify alt-da provider

[geoknee]

If DA mode is not Ethereum

• create new file that stores mapping of alt-da byte to provider name
• add-chain: env-var to specify alt-da byte
• validation: check alt-da byte and verify it matches location where data is posted.

The idea here is to handle the blue part of the Alt-DA validation check tree:

We could display it like this:

superchain/configs/mainnet/lyra.toml

name = "Lyra Chain"
chain_id = 957
public_rpc = "https://rpc.lyra.finance"
sequencer_rpc = "https://rpc.lyra.finance"
explorer = "https://explorer.lyra.finance"
superchain_level = 1
standard_chain_candidate = false
data_availability_type = "eth-da" # covered in 410
data_availability_provider = "celestia" # this is the field to add and validate

I am also open to this being an enum.
