@akhi3030 this would be the other PR we want merged before I can publish near-primitives.

This brings in all the meta transaction features to stable. To state this obvious: This is a protocol change.

However, code-wise, this should be a boring PR. Just the normal stabilization steps:

• remove all the cfg
• protocol version bump (was already done for other features)
• move the protocol feature DelegateAction to version stable 59.
• update gas snapshots for version 59 (in separate commit for easier review)

Two additional small things to take note of:

• I delete the test test_delegate_action_deserialization that has some comments regarding deserialization and protocol versions. This case is now tested in reject_valid_meta_tx_in_older_versions which was already implemented previously, I just forgot to delete the old test.
• Rosetta RPC currently ignores delegate actions. Rational is that nobody except known partners us the Rosetta RPC. They don't run it on testnet. Therefore we can wait a bit longer to get this done. Tracked in implement rosetta rpc adapter for delegate action #8469 . Eitherway, it doesn't affect the protocol and doesn't need to be linked with the stabilization PR.

The changes make sense to me.
