feat: add support for ARM64 architecture and include necessary binaries

[Bucknalla]

Summary

This PR adds comprehensive ARM64 (aarch64) Linux support to Arduino_Tools, enabling STM32duino development on ARM64 systems such as Raspberry Pi 5, Linux Docker under MacOS (ARM64) etc.

• ARM64 Linux binary support (dfu-util, hid-flash, upload_reset)
• Docker-based cross-compilation build system

ARM64 Linux systems are increasingly common in embedded development and IoT applications (Raspberry Pi 4+, cloud ARM instances, Apple Silicon via Linux VMs, etc.), but Arduino_Tools currently only provides x86_64 Linux binaries.

Adds ARM64 build script to use Docker to generate Linux ARM64 executables for:

• dfu-prefix
• dfu-suffix
• dfu-util
• hid-flash

Implements Arch/OS selecter for Linux ARM64 into maple_upload.sh and dfu-util.sh

Validation

• Ensure CI build is passed.
• Demonstrate the code is solid. [e.g. Provide a sketch]

Code formatting

• Ensure AStyle check is passed thanks CI

Closing issues

Fixes #103

Hi @Bucknalla
Thanks for this PR.

I don't want duplicate files. As the primary OS is linux I would like to kept only one directory linux/ then inside create 2 directory:
x86_64
aarch64
And update script to call binaries from the correct directory.

Ex:

    case "${UNAME_ARCH}" in
      x86_64)
        DFU_UTIL=${DIR}/linux/x86_64/dfu-util
        ;;
      aarch64|arm64)
        DFU_UTIL=${DIR}/linux-arm64/aarch64/dfu-util
        ;;
      *)
        echo "Unsupported Linux architecture: ${UNAME_ARCH}."
        exit 1
        ;;
    esac

This will ease packaging as Arduino only consider windows, macosx and linux as differentiatior.

Then move script/ folder in the src/ directory, this will avoid to release them and the src/ directory goal is to contains all related stuff to generate the binaries.
Ex: src/linux-arm64/

And accordingly update the script to properly out in the correct folder if needed.

Thanks for the quick update.
LGTM.
Not tested as I don't have such arch.

This is exciting! @fpistm do you have a release date scheduled for 2.4.0?

The release is planned soon but linked to the STM32 core 2.12.0 which is also planned soon. 😉
