Add name(), symbol(), and decimals() functions to the IERC20.sol interface as per the ERC-20 specification. These functions are marked as optional metadata functions that implementations may provide. The implementation accesses the pallet_assets::Metadata storage to retrieve token metadata (name, symbol, decimals). Changes: - Added name(), symbol(), decimals() functions to IERC20.sol interface - Implemented the three metadata functions in the Rust precompile (lib.rs) - Added comprehensive test coverage for the new metadata functions (tests.rs) - Added prdoc documentation for the changes
