Commit Message

ci: run the ARM64 job on a native ubuntu-24.04-arm runner (drop QEMU) (#1065)

The "Linux ARM64 (GCC cross)" job cross-compiled natively but ran ctest under
qemu-user-static, emulating every ARM64 test binary on x86 (~10-50x slower than
native). That emulated test execution -- which ccache cannot accelerate -- dominated
the job's wall-clock (e.g. ~17 min vs ~6.5 min for native Linux x64 on #1055).

GitHub now offers free hosted ARM64 runners for public repos, so run the job natively:
os -> ubuntu-24.04-arm, and drop `cross: aarch64` / the toolchain file so the QEMU
install step (gated on matrix.cross == 'aarch64') and the cross toolchain no-op. The job
now builds with the runner's native g++ and runs the tests natively -- faster, higher
fidelity (real ARM64 execution, not emulation), and ccache actually helps. Renamed to
"Linux ARM64 (GCC native)".

cmake/toolchains/aarch64-linux-gnu.cmake is now unused by CI but kept for local
cross-compilation. RISC-V and POWER keep their QEMU cross jobs (no native runners).
Branch protection lists no required status checks, so the job rename is safe.
