Fix ARM64 ABI notes: eliminate std::pair<double,double> from function signatures in bitbots_localization

[jaagut]

GCC 10.1+ emits ABI compatibility notes on AArch64 for any function with std::pair<double, double> in its ABI (return type or by-value parameter) when compiled with C++17. These notes blocked clean ARM64 CI builds.

Proposed changes

Replaced all std::pair<double, double> occurrences in function ABI boundaries with output parameters or separate doubles:

• tools.hpp/cpp — cartesianToPolar and polarToCartesian now use output parameters instead of returning a pair:

  // Before
  std::pair<double, double> cartesianToPolar(double x, double y);
  // After
  void cartesianToPolar(double x, double y, double& angle, double& radius);

• map.hpp/cpp — getObservationCoordinatesInMapFrame no longer takes a pair or returns one; uses individual input doubles and output parameters
• StateDistribution.hpp/cpp — RobotStateDistributionStartLeft replaces std::pair<double, double> field_size member with field_size_x_ / field_size_y_ doubles; constructor updated accordingly
• MotionModel.cpp, ObservationModel.cpp, localization.cpp — all call sites updated to match new signatures

Addressed in commit 58895ef.

• Initialized gps_header_sum in yesense_driver.cpp to remove the -Wmaybe-uninitialized warning.
• Replaced the three std::make_pair(field_dimensions_.x, field_dimensions_.y) calls in localization with explicit std::pair<double, double>{...} construction to eliminate the ARM/GCC stl_pair.h ABI diagnostic path.

Fixed in commit 02e8a7b.

I removed the remaining std::pair<double, double> ABI diagnostics in bitbots_localization by switching pair parameters to const std::pair<double, double>& where applicable and replacing remaining std::make_pair(...) calls with direct pair initialization.

No UI changes were made (no screenshot applicable).

Pull request overview

This PR expands the repository CI to run on an ARM64 GitHub Actions runner and includes a handful of C++ adjustments likely intended to address stricter ARM toolchain diagnostics (e.g., uninitialized variables and unnecessary copies).

Changes:

• Run the CI build/test job on both ubuntu-latest and an ARM64 runner via a workflow matrix.
• Initialize an otherwise uninitialized variable in the Yesense driver.
• Reduce copying in localization utilities by switching std::make_pair/by-value parameters to brace-init and const& parameters.
