[RUST][FRONTEND] refactoring builder to use a derive

[ehsanmok]

Use derive_builder for tvm_frontend::Function for less boilerplate codes. Proper config is required to make the return buffer accepts at most one value. TODO #2292.

@nhynes don't think #[derive(Builder)]] can add the proper fields in builder struct needed for Function. It is merely for very common type of builders. Currently, derive_builder only uses the fields of the underlying struct, but the rather minimal signature of the current function::Builder is

pub struct Builder<'a> {
    pub func: Option<Function>,
    pub arg_buf: Option<Box<[TVMArgValue<'a>]>>,
    pub ret_buf: Option<Box<[TVMRetValue]>>,
}

with completely different fields, in particular arg_buf and ret_buf. So my conclusion is that the derive_builder is not mature enough to handle our case.

Side note: In my code, I've pretty much followed std::process::Command construct.

Discussed here and will plan for runtime-frontend compatibility.
