Feature Summary
This pull request adds the Custom Signature page under the Account tab.
The Custom Signature page allows the user to submit a transaction that was signed with an Ethereum private key and use it as a native ECDSA account in Substrate. Plus, you are able to use MetaMask for signature requests, which allows users to use their Ethereum address inside Ledger and Trezor to create a transaction.

Notable Changes
assertbrowser polyfill that is used by theethereumjs-utilpackagecustom-signaturepage that will be available for chains that implement thecustom-signaturespallet (https://github.com/PlasmNetwork/Plasm/tree/dusty/frame/custom-signatures) asEthCall(https://github.com/PlasmNetwork/Plasm/blob/feature/vectorized-custom-signatures/bin/node/runtime/src/lib.rs#L649)Usage
Currently, this page is made with MetaMask in mind. Most browser-injected ethereum wallets that use the
window.ethereumobject and accept thepersonal_signmethod should be compatible, but please understand that there may be unexpected errors.You can learn more about the usage from this doc: https://docs.plasmnet.io/build/metamask-signatures
