Add Xcode 26 CI jobs for iOS and macOS

Replace the pipeline-level XCODE_VERSION variable with an explicit
xcodeVersion parameter on each Apple job template (ios, macos,
test_install_ios, test_install_macos). Every Apple job now passes
the Xcode version directly, making it easy to test different versions
side by side.

New jobs: MacOS_Xcode26 and iOS_Xcode26 (Xcode 26.3, macOS-latest).
