Build: Add Apple Silicon support for irteus

This commit updates the build system for the irteus module to enable native compilation on Apple Silicon (arm64) architecture.

The irteus/Makefile.Darwin is modified to:

• Automatically detect the arm64 architecture.
• Set the appropriate compiler flags (e.g., -Daarch64).
• Include the standard Homebrew library and header paths (/opt/homebrew/...) to find dependencies.

quick start

make
source bashrc.eus
irteusgl irteus/demo/demo.l
(dual-arm-ik)

I added macos-x test and passed the tests.
catkin test is failing because of GPG-key expiration.
So I also sent a PR to fix catkin test. #649 Please check it.
