Implement Error and ErrorCode for Rust

[youyuanwu]

Description

Rust Api typically returns Result<T,Error> where Error contains the error details of the api failure.
This PR implements ErrorCode enum type which can be easily converted from FFI error numbers, and Error type which produces decent error message when printed or formated. For example:

        let err = Error::new(ErrorCode::QUIC_ERROR_ABORTED);
        assert_eq!(format!("{err}"), "QUIC_ERROR_ABORTED (0x80004004)");

Changes all Apis to return Result<T,Error> instead of Result<T,u32> and removed all redundant code.

Testing

Added unit tests for error code conversion and formating.
