feat: switch FOXy from web3 to ethers and JsonRpcBatchProvider

[gomesalexandre]

Description

• Fully plumb through web
• getXYZGas -> getXYZFees/Estimate vernacular in diffed methods
• Scrutinize derp API and see if there's anything to improve to ease bringing it to web soonish
• shouldUseEip1559Fees

This PR:

• Switches from web3.js to ethers.js in investor-foxy, with revamped consumption to accommodate for it
• bumps ethers to a unified 5.7.2 version across packages to ease the bundle size of having multiple transient/dependencies for ethers
• uses the JsonRpcBatchProvider so that FOXy Ethereum JSON-RPC calls are batched
• adds a 5% gas limit buffer to ensure Txs go through - debugged through Tenderly and both our node and ethers tend to slightly underestimate the gas limit - we were somehow lucky with web3.js because they use different calculations, but our estimations don't cut it anymore
• handles EIP-1559 gas fees spec when supported by wallet
• improves HDWallet/chain-adapters types through investor-foxy and web to be narrowed down to ETHWallet / EVMBaseAdapter
• cleans up investor-foxy:
  • moves from ethers gasPrice and gasLimit estimations to unchained estimations, which should be more accurate
  • uses fees vernacular vs gas vernacular in fees estimation methods, which now return a FeeDataEstimate
  • removes buildTxToSign and use chain-adapters buildCustomTx instead
  • removes getGasPriceAndNonce, which isn't needed anymore now that we use chain-adapters so nonce will be correctly gotten there, and gas price is now useless because we use fees estimation

While at it, replaces all instances of JsonRpcProvider in web/packages to be JsonRpcBatchProvider, which will provide implicit batching whenever possible.

Risk

FOXy might be borked - tested deposit approval and deposit Txs through MM, and ran both instant and delayed withdraw ones through Tenderly, which were happy. Was unable to test claims

Testing

• Fully regression test FOXy

Engineering

• Some requests from investor-foxy will be implicitly batched, e.g getRebaseHistory:
