Rollup merge of #126424 - Enselic:sort-target-features, r=lqd 
Also sort `crt-static` in `--print target-features` output

I didn't find `crt-static` at first (for `x86_64-unknown-linux-gnu`), because it was put at the bottom of the large and otherwise sorted list.

Fully sort the list before we print it.

Note that `llvm_target_features` starts out and remains sorted and does not need to be sorted an extra time.

On my machine the diff is just:

```

I couldn't find a ui test that tested this output. Let's see if CI finds a regression tests.

README.md

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
