Rollup merge of #92933 - bjorn3:no_bin_lib_mixing, r=estebank
Deny mixing bin crate type with lib crate types

The produced library would get a main shim too which conflicts with the
main shim of the executable linking the library.

```
$ cat > main1.rs <<EOF
fn main() {}
pub fn bar() {}
EOF
$ cat > main2.rs <<EOF
extern crate main1;
fn main() {
    main1::bar();
}
EOF
$ rustc --crate-type bin --crate-type lib main1.rs
$ rustc -L. main2.rs
error: linking with `cc` failed: exit status: 1
