This commit changes the `tracing_subscriber` initialization in `rustc_driver` so that the `WARN` verbosity level is enabled by default when the `RUSTC_LOG` env variable is empty. If the `RUSTC_LOG` env variable is set, the filter string in the environment variable is honored, instead. Fixes #76824 Closes #89623 cc @eddyb, @oli-obk |

The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
