Pull Request Overview
This PR removes the unused C++ Build Mode None (BMN) feature flag and its associated logic. The feature flag CODEQL_EXTRACTOR_CPP_BUILD_MODE_NONE is no longer needed since C++ BMN now works automatically when build-mode: none is configured.
Key Changes
- Removes confusing log message that would always appear when c-cpp was configured, regardless of the actual build-mode value
- Eliminates the unused CppBuildModeNone feature flag from the feature flags enum and configuration
- Cleans up related initialization logic in the init-action module

Setting CODEQL_EXTRACTOR_CPP_BUILD_MODE_NONE no longer has any effect. C++ BMN will work whenever build-mode: none is configured for it.
This PR removes a confusing log message that would result in Setting C++ build-mode: none to false getting logged whenever c-cpp was configured as language, regardless of what value was provided for the build-mode input.
Since the FF involved in the check isn't used elsewhere in the Action, this PR also removes it.
