Auto merge of #116837 - oli-obk:smir_run_macro, r=spastorino

Avoid having `rustc_smir` depend on `rustc_interface` or `rustc_driver`

This is done by moving all the logic into a macro that performs the entire "run" operation in one go.

This makes rust-lang/rust#116806 obsolete

as a follow up we should make the macro usable without manually having to write

```rust
#[macro_use]
extern crate rustc_smir;
extern crate stable_mir;
extern crate rustc_driver;
extern crate rustc_interface;
use rustc_smir::rustc_internal;
```

in every crate that uses the macro.

r? `@spastorino`
