build: Make compatible with Debian Bullseye

This commit is a bit bigger than it could have: Meson changes could have gone in separately from CI and Debian. This commit looks more complicated than it should reasonably be. Alas, Cargo is a piece of work, and it doesn't let honest people just choose different versions of dependencies, leading to a cascade of misery. Several things were tried to curb the disaster: - Cargo [feature] supports choosing dependencies, but doesn't support specifying dependency versions - Cargo has a cfg() syntax in sections for choosing dependencies by build options, but it explicitly doesn't support selecting on features… - Cargo allows choosing different dependencies based on features, so perhaps dependencies with different versions could live in stub crates pulled in as needed? Nope! If a dependency doesn't exist in the repo (and that's the point here), Cargo throws up its hands. This means Cargo.toml needs to be generated based on the build type. More misery: - we lose the simplicity of just doing `cargo.sh` for simple housekeeping like deps updates. HACKING.md was updated to reflect that. Perhaps that's inevitable - build options need to be like this. - Some flaky adjustments needed in `cargo.sh` because of an additional argument that can be mistaken for an argument to the exec in `cargo run`. - Specifying a custom `Cargo.toml` means Cargo can no longer find any tests, examples, benchmarks, or binaries, because it searches relative to the directory of `Cargo.toml`, which is now the build dir. Extra care needed to not forget about them now. As soon as Cargo allows anything better for managing deps versions, the above should be undone in its favor. Good side is that a couple bugs went away: - build flags not always making it to Cargo - arm64 builds were optional while they shouldn't - test layouts in unit tests are loaded from an explicit directory now The Bullseye versions of dependencies are canonical now, Buster considered legacy.
