Dependencies Option Conflict Detection.

[PengZheng]

Key Changes

1. Shift from Deduction to Detection in conanfile.py

• Removed Automatic Option Setting: The code that used to force dependencies (like libzip, libcurl, openssl, etc.) to be shared=True based on Celix options has been removed.
• Implemented validate() Logic: A new validation loop was added to the validate() method. It checks if the current configuration (e.g., build_utils=True) matches the actual state of the dependencies.
• Detailed Error Reporting: If a dependency is not configured as required (e.g., if libcurl is static but Celix needs it shared), Conan now throws a ConanInvalidConfiguration error with a clear message explaining which Celix option requires which dependency setting.

2. Infrastructure & Workflow Updates

• CI Configuration: Since Conan no longer automatically sets these options, the GitHub Actions workflows (e.g., ubuntu.yml, macos.yml) were updated to explicitly pass -o *:shared=True and -o mosquitto/*:broker=True. This ensures that the CI environment continues to use the correct shared library configurations.
• Documentation: The building instructions (e.g., dev_celix_with_clion.md) were updated to reflect Conan 2.x usage.

Why this change was made

Automatic dependency option deduction is both expensive (NP-hard) and completely broken (for conan 2.x). There is a known limitation in Conan 2, where attempting to modify dependency options from a downstream package (Celix) can lead to graph inconsistencies or unexpected behavior. By moving to "conflict detection," the responsibility of providing a compatible graph is shifted to the user (or the CI profile), while the conanfile.py acts as a guard to ensure requirements are met before building.

Note that to make dependency option deduction to work in my day job, we have to patch Conan 1.x (without any upstream blessing) to redraw the dependency graph wherever an option conflict is encountered. Therefore, it is slow with hundreds of packages, each of which can have dozens of options.

Verification of the Change

This PR implemented this following suggestions from a Conan issue (conan-io/conan#19692), ensuring that the Celix recipe is more robust and compliant with modern Conan standards.
