Feat riscv llvm and cranelift

[ptitSeb]

Description

• Add RISC-V support for the LLVM compiler
• Add RISC-V support for Cranelift compiler
• Update rust toolchain to 1.65

Some tests have been disabled specificaly for RISCV. Thoses tests will need to be debug later.

The migration to 1.65 implied removing the [profile.dev] profile from main Cargo.toml. It contained only split-debuginfo=unpacked that is unsupported on Windows and just fail the build. The split-debug info will be default value now (so "off" on Linux, and "packed" on Windows and MacOS). If it's an issue, it can be forced by setting env. var., like CARGO_PROFILE_DEV_SPLIT_DEBUGINFO=packed in Makefile or CI Actions.

Cranelift recently added also support for RISC-V, it might be interesting to also enable and test it @ptitSeb

Yes, I have seen that, but I think I'll separate it from this ticket and create 2 more tickets: 1. update cranelift 2. add riscv support

Other than my suggestions, the PR looks good

RISC-V here we come, landing this will be awesome!

Just a few nitpicks.

Regarding the large error: the error is not in any hot path, so the large error should be fine, just having the annotation everywhere is pretty annoying.

Because users will also get this error if they use clippy, not just us.
