  1. Add lifetime container attribute for user-provided lifetime 

    This PR is for discussion and related to serde-rs#2190. As discussed there, the benefit is not obvious (except for providing more control to the user).

With this PR, a user can use `#[serde(lifetime = 'a)]` to control the lifetime of the implementation of `Deserialize`. In particular, the user is now able to control all the implementation parameters when using `#[serde(bound = "", lifetime = 'a)]`.

See https://github.com/ia0/wasefire/blob/ccf7bc30ac8440b30981b2f39b734de10d1a037c/crates/protocol/src/lib.rs#L65 for an example in real code.
