Support EIP-712 as the preliminary standard for meta-tx signing in NEAR

[ethernian]

Currently, it is impossible to sign any meta-tx in NEAR. This is a blocker for many use cases.

Please accept EIP-712: Typed structured data hashing and signing as a preliminary standard now and let MyNearWallet implement it.

Any NEAR-specific extensions can be elaborated on later.

Hey, @ethernian thank you for raising this issue.

At the moment there's no standard/NEP for Meta Transactions in NEAR.
The work on a NEP for this has already started and you can follow the progress of it in this PR: near/NEPs#366

Until the work on the above NEP is finalized and merged we can not make any changes on this repo related to meta-tx.

Meta-transactions are now supported on chain, we have already added an option to pass the relayerUrl to wallet selector modules: #780 , at the moment no other implementation/changes is needed in wallet-selector.
