Omni wheel drive odometry update

[Devdoot57]

Description

This PR updates the omni_wheel_drive_controller odometry implementation to use double dt for integration instead of relying on rclcpp::Time (matching #1854). It also introduces a comprehensive gtest suite to verify the holonomic kinematics and integration math (matching #2099).

This rolls out the architectural improvements requested in #2039 for the omni-wheel base.

Changes:

• Odometry API: Deprecated updateFromPos, updateFromVel, and updateOpenLoop. Replaced with update_from_pos, update_from_vel, and try_update_open_loop.
• Controller Loop: Updated the main controller update to account for the above mentioned changes.
• Testing: Added test_odometry.cpp covering:
  • Independent holonomic Y and X movements.
  • Exact arc integration for simultaneous X, Y, and rotational velocities.
  • Boundary checks for small dt rejection.
