Auto merge of #46503 - Aaron1011:librustdoc_log, r=Mark-Simulacrum

Remove librustdoc dependency on log This change should have been included in PR #46386. Since librustdoc doesn't explicitly depend on internal crates (such as librustc_driver) through its Cargo.toml, it ends up using the sysroot to resolve them. By removing the dependency on 'log', we ensure that the syroot is used to resolve `log` as well. This ensures that only one version of log is in use, so that `env_logger::init()` enables all uses of `log!` macros.
