cargo new --bin[=NAME] should be allowed

[SoniEx2]

e.g. (assuming #5431 )

cargo new --lib --bin --bin=hello crate

crate/
|_ Cargo.toml
\_ src/
   |_ lib.rs
   |_ main.rs
   \_ bin/
      \_ hello.rs

Hm, this definitely escalates.

It might be a nice idea to implement this as an external subcommand, cargo new-target --bin=hello, which adds bin/lib/test etc to existing target.

This would support both cargo new --lib --bin=crate crate and cargo new --lib --bin crate, is the idea.

Closing in favor of #5151
