Migrate `cross-lang-lto-upstream-rlibs`, `long-linker-command-lines` and `long-linker-command-lines-cmd-exe` `run-make` tests to rmake

Part of rust-lang#121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).

The `long-linker` tests are certainly doing something... interesting - they summon `rustc` calls with obscene quantities of arguments and check that this is appropriately handled. I removed the `RUSTC_ORIGINAL` magic - it's equivalent to `RUSTC` in `tools.mk`, so what is the purpose? Making it so the massive pile of flags doesn't modify rustc itself and start leaking into other tests? Tell me what you think.
