Auto merge of #126712 - Oneirical:bootest-constestllation, r=<try>

Migrate `relocation-model`, `error-writing-dependencies` and `crate-name-priority` `run-make` tests to rmake

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

Needs MSVC try-job due to #28026, almost guaranteed to fail, but let's see anyways.

try-job: aarch64-gnu
`/* try-job: x86_64-msvc */`
try-job: x86_64-apple-1
try-job: armhf-gnu
try-job: test-various
