Migrate `libs-through-symlink` to rmake.rs

Part of rust-lang#121876.

This PR migrates `tests/run-make/libs-through-symlink/` to use rmake.rs.

- Regression test for rust-lang#13890.
- Original fix PR is rust-lang#13903.
- Document test intent, backlink to rust-lang#13890 and fix PR rust-lang#13903.
- Fix the test logic: the `Makefile` version seems to not actually be exercising the "library search traverses symlink" logic, because the actual symlinked-to-library is present under the `$(TMPDIR)` directory tree when `bar.rs` is compiled, because the `$(RUSTC)` invocation has an implicit `-L $(TMPDIR)`. The symlink itself was actually broken, i.e. it should've been `ln -nsf $(TMPDIR)/outdir/$(NAME) $(TMPDIR)` but it used `ln -nsf outdir/$(NAME) $(TMPDIR)`. The rmake.rs version now explicitly separates the two directory trees and sets the CWD of the `bar.rs` rustc invocation so that the actual library is *not* present under its CWD tree.

I.e. it is now

```
$test_output/           # rustc foo.rs -o actual_lib_dir/libfoo.rlib
    actual_lib_dir/
        libfoo.rlib
    symlink_lib_dir/    # CWD set; rustc -L . bar.rs
        libfoo.rlib --> $test_output/actual_lib_dir/libfoo.rlib
```

tests: Port `translation` to rmake.rs

Part of rust-lang#121876.

This PR partially supersedes rust-lang#129011 and is co-authored with `@Oneirical.`

## Summary

This PR ports `tests/run-make/translation` to rmake.rs. Notable changes from the Makefile version include:

- We now actually fail if the rustc invocations fail... The Makefile did not have `SHELL=/bin/bash -o pipefail`, so all the piped rustc invocations to grep vacuously succeeded, even if the broken ftl test case actually regressed over time and ICEs on current master.
    - That test case is converted to assert it ICEs with a FIXME backlinking to rust-lang#135817.
- The test coverage is expanded to not ignore windows. Instead, the test now uses symlink capability detection to gate test execution.
- Added some backlinks to relevant tracking issues and the initial translation infra implementation PR.
