build: integrate central S-CORE toolchain configuration

[srinivasugithub]

📥 S-CORE Toolchain Configuration Integration

This PR integrates the central S-CORE toolchain configuration from the reference eclipse-score/module_template repository into the score_lifecycle repository.

Our integration ensures that all central toolchains and configurations are adopted 100% unchanged and are elegantly separated from repository-specific additions and overrides.

🌟 Key Changes

1. MODULE.bazel Alignment:

   • Replaced previous custom toolchains with the central S-CORE Toolchains (DO NOT MODIFY) section.
   • Registered the local/specific score_gcc_aarch64_toolchain separately under a clearly defined "Repository-specific toolchain additions" section.
   • Resolved a package scope issue by explicitly importing score_qcc_aarch64_toolchain_pkg inside our repository-specific section of MODULE.bazel.

2. Imported Central .bazelrc Configuration:

   • Created score.bazelrc/score_toolchain.bazelrc exactly matching the reference file.
   • Loaded the configuration gracefully inside .bazelrc via try-import.

3. Optimized .bazelrc profiles:

   • Refactored and simplified x86_64-linux to cleanly inherit from --config=score-linux-x86_64.
   • Refactored and simplified x86_64-qnx to cleanly inherit from --config=score-qnx-x86_64.
   • Completely deleted redundant configuration and the previous toolchain_common block.
   • Retained arm64-linux and arm64-qnx as separate repository-specific additions (inheriting from _score_common).

🔮 Identified Candidates for Future Centralization

We identified these repository-specific components that could be candidates for future S-CORE integration into module_template:

1. aarch64 Linux GCC Toolchain: Other projects targeting ARM64 Linux systems will benefit from standardizing this.
2. QNX IFS (imagefs) Toolchain: Useful to standardise image generation across QNX-based projects.
3. Sanitizer Configurations: Our custom ASAN, TSAN, UBSAN, and LSAN setup is robust and general enough to be centralized.

🧪 Verification Done

• C++ builds: Successfully compiled //examples/cpp_lifecycle_app using --config=x86_64-linux on host.
• C++ unit tests: Successfully executed //score/launch_manager/src/daemon/src/common:identifier_hash_UT with --config=x86_64-linux.
• Bazel Parsing: Verified that all config profiles load successfully with no syntax or constraint resolution issues.

Fixes #448

The configuration will not work if the file is missing, so this should be a hard dependency:
