const support in #[server] macro endpoint field

[tetuaoro]

Is your feature request related to a problem? Please describe.
No.

I like to use const wherever I can in the code. So I tried to use a const in the macro #[server] but it's not supported.

Example :

const HELLO_ROUTE: &str = "...";

#[server(endpoint = "HELLO_ROUTE")]
pub async fn hello() -> Result<...> {...}

Of course, the constant is used twice in the code, just like in middleware. So why not implement #[server(fullpath = "...")]. This field overrides the prefix and endpoint fields.

EDIT: maybe, fullpath is another feature.

PR welcome. @rakshith-ravi raised a similar idea recently I believe. It would require replacing the current form of constant string concatenation, which uses const_format::concatcp!() and only accepts literals, with some kind of const string slice concatenation like this pair.

Yusss. I have a very basic wip with me. Haven't found too much time to work more on it. Happy to collaborate with you @tetuaoro if you're interested in working on this. I'm here on discord (you can find me on the Leptos discord as well)
