描述

Allow self impl for contracts as a shorthand for an anonymous ABI spec. The point is to not have to write an ABI type for very small contracts.

This:

contract;
impl Contract {
    fn foo() -> u64 { 0 }
}

Should produce the same binary and ABI spec as:

contract;
abi MyAbi {
    fn foo() -> u64;
}
impl MyAbi for Contract {
    fn foo() -> u64 { 0 }
}

研究方向
The feature requires modifying the Sway compiler's parser to allow `impl Contract` without an explicit ABI declaration. Likely files include `sway core/src/language/parsed/expression/` and `sway parse/src/parser.rs`. The implementation should desugar `impl Contract` into an anonymous ABI as shown in the issue. Review existing ABI handling and contract implementation code paths to ensure compatibility.
