Rollup merge of #89634 - hawkw:eliza/enable-err-warn, r=oli-obk
rustc_driver: Enable the `WARN` log level by default

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
