Rollup merge of #91606 - joshtriplett:stabilize-print-link-args, r=pnkfelix

Browse source 
Stabilize `-Z print-link-args` as `--print link-args`

We have stable options for adding linker arguments; we should have a
stable option to help debug linker arguments.

Add documentation for the new option. In the documentation, make it clear that
the *exact* format of the output is not a stable guarantee.
