Update send and confirm state management, and tx controller gas defaults, for EIP1559 (#11549)
wip

Documentation improvements for send slice support of EIP1559

Remove console.log in send duck

Property lookup safety improvement in selectors/confirm-transaction

Add code accidentally removed in rebase

Update addTxGasDefaults and _getDefaultGasFees to work with new estimate types, and ensure we correctly handle gas price estimates when on EIP1559 networks (#11615)

* Fix typo

Remove console.log in send duck

* Update addTxGasDefaults and _getDefaultGasFees to work correctly with all new gas fee estimate types

* Don't show gas timing support when not on eip1559 compatible network

* Hide gas timing component on transaction screen when on a non-1559 network

* Improve comments, tests and edge case handling

* Ensure eip1559 fees are applied and updated correctly when eip1559 estimate api fails

* Lint fix

Co-authored-by: Brad Decker <git@braddecker.dev>

Remove console.log

Handle possible gasEstimateType undefined

Remove unnecessary nonce field position change in confirm-page-container-content__details
