Show the limit and attempted size when tx data size is exceeded

Currently, [geth enforces a tx size of 128kb](https://github.com/ethereum/go-ethereum/blob/master/core/tx_pool.go#L53).

If a user exceeds this, they get a pretty useless error:

It's getting easier to exceed this with sites that allow massive transaction batching, like [gem.xyz](https://www.gem.xyz/).

It would be nice if a user gets this error, for us to show a useful message on the failed transaction, like:
> This transaction was 256kb, which exceeds the limit of 128kb

Start by reviewing geth's core/tx_pool.go limit and tracing MetaMask's failed transaction error handling for transactions rejected because their data exceeds that limit. Done means the failed transaction message reports both the attempted size and the 128kb limit, using the example wording as the expected outcome.
