Subject: [PATCH 1/2] Refactor PR CI

Upstream tooling has several breaking changes that limit our ability to
cross compile on CI.

- MIPS downgraged to Tier 3 and not providing rust-std pre-compilation
- MIPS having `-lunwind` errors on nightly when running `-Z build-std`
- Stable cross for Android lacking `-lunwind` on the container

This commit separate the problematic pipelines into their own workflow,
so it does not interrupt the build matrix of stable cross compilation
tools.

Furthermore, to alleviate the MIPS Tier 3 downgraged, we now pin the
MIPS pipeline to Rust 1.71, which still had MIPS as Tier 2.
