According to MDN (https://developer.mozilla.org/en-US/docs/Web/CSS/font-size), > To maximize accessibility, it is generally best to use values that > are relative to the user's default font size. > Defining font sizes in px is not accessible, because the user cannot > change the font size in some browsers. Note that changing font size (in browser or OS settings) is distinct from the zoom functionality triggered with Ctrl/Cmd-+. Zoom functionality increases the size of everything on the page, effectively applying a multiplier to all pixel sizes. Font size changes apply to just text. For relative font sizes, we could use `em`, as we do in several places already. However that has a problem of "compounding" (see MDN article for details). The compounding problem is nicely solved by `rem`, which make font sizes relative to the root element, not the parent element. Since we were using a hodge-podge of pixel sizes, em, rem, and percentage sizes before, this change switching everything to rem, while keeping the same size relative to our old default of 16px. 16px is still the default on most browsers, for users that haven't set a larger or smaller font size.
Currently the output of a command like `./x.py build --stage 0 library/std` is this:
```

I find the part before the "Building stage0 std artifacts" a bit confusing.
After this commit, it looks like this:
```

The "Building rustbuild" label makes it clear what the first cargo build
invocation is for. The indentation of the "Submodules updated" line
indicates it is a sub-step of a parent task.
They're a bit out of date, and overly complicated.

Part of rust-lang#59845. Note: this will conflict with rust-lang#92404. We should merge that first (once it's done) and I'll resolve the merge conflicts. r? `@GuillaumeGomez` Demo: https://rustdoc.crud.net/jsha/font-size-access/std/string/struct.String.html

Extract init_env_logger to crate
I've been doing some work on rustc_ast_pretty using an out-of-tree main.rs and Cargo.toml with the following:
```toml
[dependencies]
rustc_ast = { path = "../rust/compiler/rustc_ast" }
rustc_ast_pretty = { path = "../rust/compiler/rustc_ast_pretty" }
rustc_span = { path = "../rust/compiler/rustc_span" }
```
Rustc_ast_pretty helpfully uses `tracing::debug!` but I found that in order to enable the debug output, my test crate must depend on rustc_driver which is an enormously bigger dependency than what I have been using so far, and slows down iteration time because an enormous dependency tree between rustc_ast and rustc_driver must now be rebuilt after every ast change.
I pulled out the tracing initialization to a new minimal rustc_log crate so that projects depending on the other rustc crates, like rustc_ast_pretty, can access the `debug!` messages in them without building all the rest of rustc.
