Tracking issue for making std-surfaced macro intrinsics available via `std::` paths

[mark-i-m]

Quoting @cramertj in #53128 (comment)

@mark-i-m Are you referring to how std-surfaced macro intrinsics aren't yet usable by their std paths? e.g. This code only works if you remove std:::

fn main() {
    println!("{}", std::format_args!("{}", 5));
}

error[E0433]: failed to resolve: could not find `format_args` in `std`
 --> src/main.rs:2:25
  |
2 |     println!("{}", std::format_args!("{}", 5));
  |                         ^^^^^^^^^^^ could not find `format_args` in `std`

error: aborting due to previous error
