docker: Add new target

* Add target for cortex-m33
* Update rustc to latest (reduces firmware size by about 4k)
* Update llvm to match rust
* Vendor new deps due to new toolchain
* Update Arm GNU toolchain to 15 (further reduces by about 2k)

The short version

What changed, and why it matters

This is a routine build-system and toolchain update for the BitBox02 firmware. It adds support for a new ARM processor target (Cortex-M33), upgrades the Rust compiler, LLVM, and the ARM GNU toolchain, and pulls in newer versions of some third-party Rust libraries. There is no direct evidence in the commit of a security vulnerability being fixed or introduced. The main risk is the usual one with large toolchain and dependency updates: a small chance that compiler, library, or behavior changes could introduce subtle bugs, but nothing in the diff points to an exploitable flaw.

Recommended action

Treat as a normal maintenance commit. Verify the updated container builds correctly and that firmware tests, including unit tests and simulator tests, pass with the new toolchain. Review release notes for the upgraded Rust/LLVM/Arm toolchain versions for any known security advisories, but no immediate security action is required based on this diff alone.
