CW-551-Refactor-EVM-Chains (#1256)
* feat: Create central package for EVM chains * chore: Cleanup pubspec and add core evm dependencies * feat: Replicated core evm chain files, time to start fixing the issues * feat: Setup evm central package to handle all evm chains * feat: Link up Polygon and Ethereum wallets to the centra evm package, fix bugs and issues, and optimze for better performance * feat: Setup and adjust configs to reflect new evm configurations * Remove unneeded file * fix: Changes done while re-reviewing entire structure and refactor * fix: Add evm chain wallet path to imports in configure file * feat: Adjust implementation of parent class, remove unneeded files, remove windows, linux and mac directories, restructure the evm child classes * fix: Make EVMChainWallet a central abstract class and adjust accordingly * fix: Adjust transaction info, restructure EVMWalletChain to be an abstract, adjust external facing interfaces for polygon and ethereum, adjust configuration for ethereum and polygon in configure file * fix: Testing issues * fix: Add localization for nft tile and details page texts and add dashes for null responses * fix: merge conflicts * Minor fixes for building Monero.com --------- Co-authored-by: OmarHatem <omarh.ismail1@gmail.com>
