Rollup merge of #60401 - JohnTitor:rename-log, r=davidtwco

Rename `RUST_LOG` to `RUSTC_LOG`

cc: #57985

I think we should also change these submodules:

- rustc-guide
- Cargo (rename to `CARGO_LOG`, cc: https://github.com/rust-lang/cargo/pull/6605, https://github.com/rust-lang/cargo/issues/6189)
- miri
- rls
- rustfmt
