Allow submission of transactions with dapp suggested gas fees, while estimates are loading (#11858)
* Allow submission of transactions with dapp suggested gas fees, while estimates are loading

* Allow editing of transactions with dapp suggested feeds, while estimates are still loading

* Ensure that advanced gas is always editible inline when gas is loading

* Ensure that insufficient balance error is shown when gas is loading if the user has customized the gas

* Only set gas price insufficient errors if the current network is non-eip-1559, or the txparams actually have a gas price

* Remove unnecessary param

* lint fix

* ensure insufficient balance warning is showing when loading

* Ensure that eip1559 network transactions do not combined eip1559 and non-eip1559 gas fee properties

* Lint fix
