Updates makefile with aarch64 targets

[future-highway]

• Created makefile commands for --target aarch64-unknown-linux-musl where needed
• Updated make test to use --target x86_64-unknown-linux-musl when not testing auraescript
• Removed make clean-auraescript and make clean-auraed (they don't do anything; left over from when we had multiple repos)
• Reactivated the tests and commented for when they are ignored
• Updated M1 development guide

---

Multiple tests that are ignored in CI are failing, in relation to cgroups-rs. An example output (others are the same):

---- runtime::cell_service::cells::cells::tests::test_allocate stdout ---- thread 'runtime::cell_service::cells::cells::tests::test_allocate' panicked at 'inner from builder: Error { kind: WriteFailed("cpu.weight", "0"), cause: Some(Os { code: 34, kind: Uncategorized, message: "Result not representable" }) }', auraed/src/runtime/cell_service/cells/cgroups/cgroup.rs:64:29

Seems like we need to update our validation. (edit: may just be the tests, as they skip validation)
