PR description

The main goal of this PR is to make clearer the reason a blob tx is not selected during block creation, with the introduction of 2 specifics not selected results:

  • BLOBS_FULL = The block already contains the max number of allowed blobs.
  • TX_TOO_LARGE_FOR_REMAINING_DATA_GAS = The transaction has not been selected since there is not enough remaining data gas in the block to fit the blobs of the tx.

and to achieve that it was clearer to extract the blob tx selection login in its own class BlobSizeTransactionSelector, while doing that a small bug was fixed, since data gas used was added to gas used when computing if a block was full, while these 2 gas types are independent, see here for details.

adding blobGasUsed is incorrect here, since here we only want to check the gas used and not the data gas used

Can we use the term blob gas instead of data gas? for the variables and transaction selection reasons?

from reading the description this PR is doing 4 very excellent things, but would be easier to review as several smaller PRs

Fair point, splitting in 3 PRs:

first one Stop transaction selection on TX_EVALUATION_TOO_LONG
second one Fix and restore disabled block creation unit tests

the fix to blob gas is related to this refactor so make sense to keep in this PR

I also like more blob gas because is more common, and I will rename to it, but in many other places we have data gas like the DataGas type, so it is up to another PR to align the naming everywhere
